Plataformização do trabalho em mercado periférico: uma análise ergológica de implicações nas condições de vida e de trabalho de motoristas e entregadores/as no contexto brasileiro / Platformization of labor in the peripheral market: an ergological analysis of implications for the living and working conditions of drivers and delivery workers in the Brazilian context

Em um quadro em que se constata a ampliação exponencial da exploração do trabalho por plataformas digitais e de discussões sobre a relação de funcionalidade entre os mercados centrais e periféricos de trabalho, propõe-se aqui uma análise do trabalho de entregadores/as e motoristas por aplicativos no contexto social, político e econômico brasileiro. O objetivo é identificar normas e valores em circulação nas experiências dos trabalhadores no entrecruzamento de seus contextos de vida e trabalho. Com base no referencial teórico da Ergologia, realizou-se uma pesquisa qualitativa com vistas à aproximação das vivências e atividades dos sujeitos por meio de entrevistas semiestruturadas. Os resultados apontam valores em circulação nos debates de normas que entram em conflito entre o ideal de liberdade anunciado pelas empresas-plataformas, o controle e o direcionamento do trabalho operado por elas via gerenciamento algorítmico e a iminência de perda da fonte de sustento. Afirma-se, a importância da construção de caminhos coletivos de produção da saúde, seja no âmbito macrossocial ou na experiência concreta e cotidiana de trabalho

In a context in which the exponential growth of the exploitation of work by digital platforms and the discussion on the relation of functionality between central and peripheral labor markets, the authors propose an analysis of the work of delivery workers and app drivers in the Brazilian social, political, and economic context. They aimed to identify norms and values in workers' experiences at the intersection between the contexts of their life and work. Based on the theoretical framework of Ergology, a qualitative research was carried out to approach subjects' experiences and activities using semi-structured interviews. Results point to values found in the norms that conflict with the ideal of freedom heralded by online platform companies, the control and directing of the work operated by these companies via algorithmic management, and the imminence of loss of source of livelihood. We stress the importance of building collective paths to produce health, whether in the macro-social context or in the concrete, daily experience of work

Relação entre adesão a crenças meritocráticas e a renda familiar / Relationship between adherence to meritocratic beliefs and family income / Relación entre adherencia a las creencias meritocráticas y al ingreso familiar

A meritocracia pode ser considerada uma ideologia que coopera na justifi-cação das desigualdades entre as classes existentes no sistema econômico. Isso se dá com a valorização de características como a competitividade, a habilidade e o esforço individual, desconsiderando fatores históricos, culturais e socioeconômicos. O objetivo da pesquisa foi caracterizar a adesão a crenças meritocráticas, vinculando as respostas obtidas à condição social do partici-pante. Uma amostra de 1.233 adultos respondeu uma entrevista estruturada, indicando o grau de concordância com três sentenças a respeito do papel do esforço individual para o sucesso, a relação entre habilidade e remuneração e a desigualdade social. Os resultados indicaram que a renda dos indivíduos está associada à percepção da lógica meritocrática, posto que sujeitos com maiores rendas tenderam a questionar as generalizações, mas não deixam de aderir a sua lógica com veemência, valorizando esforço e manutenção das diferenças salariais pautadas no valor social agregado a determinadas habilidades. Já sujeitos com menor acesso a recursos demonstraram crer na meritocracia com menores questionamentos, emergindo assim as características ideológicas da meritocracia e as concepções dominantes de classes sociais mais abastadas.

Meritocracy can be considered an ideology that cooperates to justify the inequalities between the classes existing in the economic system. This is done by valuing characteristics such as competitiveness, ability and individual effort, disregarding historical, cultural and socioeconomic factors. The aim of the research was to characterize adherence to meritocratic beliefs, linking the responses obtained to the social conditions of participants. A sample of 1.233 adults completed a structured interview, indicating the degree of agreement with three sentences regarding the role of individual effort for success, the rela-tionship between ability and remuneration, and social inequality. The results indicated that the income of the individuals is associated with the perception of the meritocratic logic, since subjects with higher incomes tended to question the generalizations, but they did not stop adhering to their logic with vehemence, valuing effort and maintenance of wage differences based on social value added to certain skills. In contrast, subjects with less access to resources have shown to believe in meritocracy with less questioning, thus emerging the ideological characteristics of meritocracy and the dominant conceptions of more affluent social classes.

La meritocracia puede considerarse una ideología que coopera para justi-ficar las desigualdades entre clases en el sistema económico. Esto ocurre con la valoración de características como la competitividad, la habilidad y el esfuerzo individual, sin tener en cuenta los factores históricos, culturales y socioeconómicos. El objetivo de la investigación fue caracterizar la adhesión a las creencias meritocráticas, vinculando las respuestas obtenidas con la condición social del participante. Una muestra de 1.233 adultos respondió a una entrevista estructurada, indicando el grado de acuerdo con tres oraciones con respecto al papel del esfuerzo individual para el éxito, la relación entre la habilidad y la remuneración y la desigualdad social. Los resultados indicaron que el ingreso de los individuos está asociado con la percepción de la lógica meritocrática, ya que los sujetos con mayores ingresos tienden a cuestionar las generalizaciones, pero se adhieren fuertemente a su lógica, valoran el esfuerzo y mantienen las diferencias salariales basadas en el valor social. agregado a ciertas habilidades. Ya los sujetos con menos acceso a los recursos mostraron creer en la meritocracia con preguntas menores, surgiendo así las características ideológicas de la meritocracia y las concepciones dominantes de las clases sociales más ricas.

The Country That Never Retires: The Gendered Pathways to Retirement in South Korea.

OBJECTIVES: Among all Organization for Economic Cooperation and Development countries, South Korean older adults work until the latest age. We investigate the extent to which work experiences over the life course and family circumstances can be associated with older workers' incentives to remain in the labor force beyond the statutory pension age. We explore gender-specific patterns of labor force exit and labor force re-entry in later life. METHODS: Using panel data of South Korean older workers and retirees from 2006 to 2016, we estimate multilevel discrete-time models with random effects to predict their labor force transition process that unfolds over time. RESULTS: Results show that skilled manual workers are less likely to exit employment and more likely to re-enter the labor force. A longer history of self-employment is related to later retirement. The relationship between career characteristics and the risk of retirement is only significant for men. Late-aged employment transition among women appears to be more related to family conditions. Women who receive financial support from adult offspring are more likely to remain out of the labor force but this relationship is not pronounced among men. DISCUSSION: Policies aimed at extending working lives need to provide various types of social support to older job seekers, especially those who had low-class jobs and those without family networks.

'Intelligent' lockdown, intelligent effects? Results from a survey on gender (in)equality in paid work, the division of childcare and household work, and quality of life among parents in the Netherlands during the Covid-19 lockdown.

OBJECTIVE: The COVID-19 pandemic is more than a public health crisis. Lockdown measures have substantial societal effects, including a significant impact on parents with (young) children. Given the existence of persistent gender inequality prior to the pandemic, particularly among parents, it is crucial to study the societal impact of COVID-19 from a gender perspective. The objective of this paper is to use representative survey data gathered among Dutch parents in April 2020 to explore differences between mothers and fathers in three areas: paid work, the division of childcare and household tasks, and three dimensions of quality of life (leisure, work-life balance, relationship dynamics). Additionally, we explore whether changes take place in these dimensions by comparing the situation prior to the lockdown with the situation during the lockdown. METHOD: We use descriptive methods (crosstabulations) supported by multivariate modelling (linear regression modelling for continuous outcomes; linear probability modelling (LPM) for binary outcomes (0/1 outcomes); and multinomial logits for multinomial outcomes) in a cross-sectional survey design. RESULTS: Results show that the way in which parents were impacted by the COVID-19 pandemic reflects a complex gendered reality. Mothers work in essential occupations more often than fathers, report more adjustments of the times at which they work, and experience both more and less work pressure in comparison to before the lockdown. Moreover, mothers continue to do more childcare and household work than fathers, but some fathers report taking on greater shares of childcare and housework during the lockdown in comparison to before. Mothers also report a larger decline in leisure time than fathers. We find no gender differences in the propensity to work from home, in perceived work-life balance, or in relationship dynamics. CONCLUSION: In conclusion, we find that gender inequality in paid work, the division of childcare and household work, and the quality of life are evident during the first lockdown period. Specifically, we find evidence of an increase in gender inequality in relation to paid work and quality of life when comparing the situation prior to and during the lockdown, as well as a decrease in gender inequality in the division of childcare and household work. We conclude that the unique situation created by restrictive lockdown measures magnifies some gender inequalities while lessening others. DISCUSSION: The insights we provide offer key comparative evidence based on a representative, probability-based sample for understanding the broader impact of lockdown measures as we move forward in the COVID-19 pandemic. One of the limitations in this study is the cross-sectional design. Further study, in the form of a longitudinal design, will be crucial in investigating the long-term impact of the COVID-19 pandemic on gender inequality.

Health behaviours and psychosocial working conditions as predictors of disability pension due to different diagnoses: a population-based study.

BACKGROUND: To investigate whether the clustering of different health behaviours (i.e. physical activity, tobacco use and alcohol consumption) influences the associations between psychosocial working conditions and disability pension due to different diagnoses. METHODS: A population-based sample of 24,987 Swedish twins born before 1958 were followed from national registers for disability pension until 2013. Baseline survey data in 1998-2003 were used to assess health behaviours and psychosocial Job Exposure Matrix for job control, job demands and social support. Cox proportional hazards models were used to calculate hazard ratios (HR) with 95% confidence intervals (CI). RESULTS: During follow-up, 1252 disability pensions due to musculoskeletal disorders (5%), 601 due to mental diagnoses (2%) and 1162 due to other diagnoses (5%) occurred. In the models controlling for covariates, each one-unit increase in job demands was associated with higher (HR 1.16, 95%CI 1.01-1.33) and in job control with lower (HR 0.87, 95%CI 0.80-0.94) risk of disability pension due to musculoskeletal disorders among those with unhealthy behaviours. Among those with healthy behaviours, one-unit increase of social support was associated with a higher risk of disability pension due to mental and due to other diagnoses (HRs 1.29-1.30, 95%CI 1.04-1.63). CONCLUSIONS: Job control and job demands were associated with the risk of disability pension due to musculoskeletal disorders only among those with unhealthy behaviours. Social support was a risk factor for disability pension due to mental or other diagnoses among those with healthy behaviours. Workplaces and occupational health care should acknowledge these simultaneous circumstances in order to prevent disability pension.

Healthcare use, work loss and total costs in incident and prevalent Crohn's disease and ulcerative colitis: results from a nationwide study in Sweden.

BACKGROUND: There are limited data on population-wide assessment of cost in Crohn's disease (CD) and ulcerative colitis (UC). AIM: To estimate the societal cost of actively treated CD and UC in Sweden. METHODS: We identified 10 117 prevalent CD and 19 762 prevalent UC patients, aged ≥18 years on 1 January 2014 and 4028 adult incident CD cases and 8659 adult incident UC cases (2010-2013) from Swedish Patient Register. Each case was matched to five population comparators. Healthcare costs were calculated from medications, outpatient visits, hospitalisations and surgery. Cost of productivity losses was derived from disability pension and sick leave. RESULTS: The mean annual societal costs per working-age patient (18-64 years) with CD and UC were $22 813 (vs $7533 per comparator) and $14 136 (vs $7351 per comparator), respectively. In patients aged ≥65 years, the mean annual costs of CD and UC were $9726 and $8072 vs $3875 and $4016 per comparator, respectively. The majority of cost for both CD (56%) and UC (59%) patients originated from productivity losses. Higher societal cost of working-age CD patients as compared to UC patients was related to greater utilisation of anti-TNF (22.2% vs 7.4%) and increased annual disability pension (44 days vs 25 days). Among incident CD and UC patients, the mean total cost over the first year per patient was over three times higher than comparators. CONCLUSION: In Sweden, the societal cost of incident and prevalent CD and UC patients was consistently two to three times higher than the general population.

Influenza vaccination and absenteeism among healthy working adults: a cost-benefit analysis.

BACKGROUND: Seasonal influenza is a highly contagious infection that might lead to serious clinical complications and incurs a conspicuous socio-economic impact. Influenza vaccination is currently recommended only for specific groups of healthy adults (such as healthcare workers) even though it was demonstrated to be effective in reducing absenteeism and decreased workers' productivity during flu epidemic period. The main purpose of this study is to analyse the extent of absences due to illness following a voluntary flu immunization program among the Komatsu Italia Manufacturing company's personnel during the flu season 2017-2018. Secondly, we aimed at performing a cost-benefit analysis of the vaccination campaign from the company's perspective. STUDY DESIGN: This is an observational cohort study conducted during the period between the 14th week of 2017 and the 13th week of 2018 (from 03/04/2017 to 01/04/2018). The study population was the personnel of Komatsu Italia Manufacturing S.p.A. on duty during the study period. METHODS: For each subject the following data were collected: sex, date of birth, professional profile, seasonal influenza immunization status and sick-leave days. Sick-leave days were compared among the influenza epidemic period and the previous one between vaccinated and unvaccinated and any difference in days of absence was considered to be caused by seasonal influenza. RESULTS: Out of 408 employees, 60 (14.7%) accepted the voluntary influenza vaccination. In multivariate analysis (logistic model) an age ≥ 50 years was the only predictor for vaccination acceptance (ORM 3.11 p<0.001). During the flu period, the monthly mean of sick-leave days per employee was significantly lower among the vaccinated than the unvaccinated, respectively of 0.328 days/person vs 0.752 days/person (p = 0.022). Unvaccinated employees reported a higher average of sick-leave days during the flu period compared to the previous non-influenza period (0.752 days/month/person vs 0.337 days/month/person p <0.001). The monthly mean cost for sickness absences per employee was significantly higher for an unvaccinated subject compared to one vaccinated, respectively € 129.00 and € 54.00 (p = 0.028). The overall net saving estimated was € 314.00 per person vaccinated. CONCLUSIONS: Influenza vaccination proved to be an extraordinary preventive tool and a cost-effective intervention. However, influenza immunization seems to be unappealing among healthy adults and higher flu vaccination coverages could be achieved through educational interventions possibly addressing young employees who showed little interest in vaccination. Finally, among health promotion interventions, companies should point out the importance of flu vaccination both for the individual wellbeing and the company environment.

"It's Luck as to What Sort of Family You're Born Into" Cumulative Dis/advantage Generative Systemic Processes Across the Life Course of a Baby-Boom Birth Cohort.

OBJECTIVES: While a large body of evidence exists in support of outcomes associated with cumulative dis/advantage (CAD), individual-level experiences of the systemic processes that generate unequal outcomes have received far less attention. This study explored experiences, among members of an early baby-boom birth cohort, of CAD-generative processes within the education and housing systems and the mechanisms by which they interacted with initial social position to perpetuate inequalities. METHODS: The author conducted in-depth interviews (n = 27) with members of the Newcastle Thousand Families Study, a UK 1947 birth cohort. Longitudinal survey data enabled participant sampling on the basis of gender, occupational social class at birth and age 50, educational attainment and homeownership status at age 60. Qualitative data were analyzed using thematic analysis. RESULTS: Analysis identified two themes: Firstly, the sorting and funneling mechanisms by which the "meritocratic" education system interacted with initial social position, progressively narrowing aspirations and opportunities; and secondly, the creation in later life of winners and losers in the property market, resulting in legitimization of inequalities through a deservingness narrative. DISCUSSION: CAD has proved persistent, even among the supposedly "lucky" early baby-boom cohort. Policies to ameliorate CAD generation through education and property systems act instead to entrench advantaged social positions. Later-life outcomes can be naturalized as the product of effort-plus-ability if not seen in a whole-life context. Disruption of CAD processes requires challenging vested interest inherent in social systems.

[Was Gregor Mendel subjected to chores before becoming a monk in 1843?] / Gregor Mendel fut-il soumis à la corvée avant de devenir moine en 1843 ?

Our knowledge of the young Mendel's life prior to his admission to the monastery comes essentially from the curriculum vitae submitted in 1850. His first biographer Hugo Iltis used this document as a sort of autobiography, although the document contained various voluntary omissions and inaccuracies. We have sought the reasons for these and in so doing have discovered why Mendel's entry into religion had become ineluctable.

TITLE: Gregor Mendel fut-il soumis à la corvée avant de devenir moine en 1843 ? ABSTRACT: Après avoir suivi brillamment deux ans de cours préparatoires à la formation universitaire qui devait le mener au professorat, Gregor Mendel entre subitement dans un monastère augustin en 1843. A-t-il renoncé à son projet professoral pour devenir prêtre ou a-t-il seulement repoussé ce projet ? Afin de déterminer les raisons de son comportement, nous étudions dans cet article ses années de formation secondaire, en complétant et en corrigeant les données d'un curriculum vitae rédigé par lui-même en avril 1850, pour le joindre à une demande d'habilitation à l'enseignement secondaire.

An examination of the effects of labor efficiency on the profitability of grass-based, seasonal-calving dairy farms.

The seasonality of grass-based, seasonal-calving dairy systems results in disproportionately higher labor demands during the spring, when cows are calving, than in the remaining seasons. This study aimed to (1) examine the relationship between labor efficiency and profitability; (2) investigate strategies to reduce the hours worked per day by the farmer, family, and farm staff in the spring by having certain tasks outsourced; and (3) quantify the economic implications of those strategies. Data from an existing labor efficiency study on Irish dairy farms were used in conjunction with economic performance data from the farms. Tasks that required the highest level of farm labor per day in the spring were identified and hypothetical strategies to reduce the farm hours worked per day were examined. A stochastic budgetary simulation model was then used to examine the economic implications of employing these strategies and the effects of their use in conjunction with a proportionate increase in cow numbers that would leave the hours worked per day unchanged. The strategies were to use contractors to perform calf rearing, machinery work, or milking. Contracting out milking resulted in the greatest reduction in hours worked per day (5.6 h/d) followed by calf rearing (2.7 h/d) and machinery work (2 h/d). Reducing the hours worked per day by removing those tasks had slight (i.e., <5%) negative effects on profitability; however, maintaining the farm hours worked per day while utilizing the same strategies and increasing herd sizes resulted in profitable options. The most profitable scenario was for farms to increase herd size while contracting out milking.

Productivity Burden of Hypertension in Australia.

Hypertension increases the risk of premature death and reduces work productivity. We estimated the burden of hypertension in Australia in terms of productivity lost over the working lifetime of the Australian population. Life table models were used to estimate excess mortality, years of life lost, and productivity-adjusted life years lost among Australians with hypertension and of working age (20 to 69 years), with simulated follow-up until age 70 years. In 2017, an estimated 4.1 million working-age Australians (25.9%) had hypertension, of whom an estimated 21.6% were treated and controlled, 17.0% were treated but uncontrolled, and 61.4% were untreated. With simulated follow-up, over 149 846 excess deaths leading to a loss of over 548 794 years of life were predicted to occur in the hypertension cohort. Hypertension also caused the loss of 609 801 productivity-adjusted life years (2.4%), equating to AUD$137.2 billion in lost gross domestic product over the working lifetime. A 25% reduction in hypertension prevalence, in line with the World Health Organisation Global Action Plan targets, would lead to 155 450 productivity-adjusted life years saved over the working lifetime, whereas the adequate treatment and control of all of those with hypertension would lead to 342 538 productivity-adjusted life years saved. This equates to AUD$34.3 billion and $76.4 billion in gross domestic product retained over the working lifetime of the cohort, respectively. Our findings highlight the considerable economic burden of hypertension in Australia and that effective strategies aimed at the prevention and adequate control of hypertension are likely to pay significant economic dividends for individuals, employers, and governments in the longer term.

Productivity burden of smoking in Australia: a life table modelling study.

OBJECTIVES: This study aimed to examine the impact of smoking on productivity in Australia, in terms of years of life lost, quality-adjusted life years (QALYs) lost and the novel measure of productivity-adjusted life years (PALYs) lost. METHODS: Life table modelling using contemporary Australian data simulated follow-up of current smokers aged 20-69 years until age 70 years. Excess mortality, health-related quality of life decrements and relative reduction in productivity attributable to smoking were sourced from published data. The gross domestic product (GDP) per equivalent full-time (EFT) worker in Australia in 2016 was used to estimate the cost of productivity loss attributable to smoking at a population level. RESULTS: At present, approximately 2.5 million Australians (17.4%) aged between 20 and 69 years are smokers. Assuming follow-up of this population until the age of 70 years, more than 3.1 million years of life would be lost to smoking, as well as 6.0 million QALYs and 2.5 million PALYs. This equates to 4.2% of years of life, 9.4% QALYs and 6.0% PALYs lost among Australian working-age smokers. At an individual level, this is equivalent to 1.2 years of life, 2.4 QALYs and 1.0 PALY lost per smoker. Assuming (conservatively) that each PALY in Australia is equivalent to $A157 000 (GDP per EFT worker in 2016), the economic impact of lost productivity would amount to $A388 billion. CONCLUSIONS: This study highlights the potential health and productivity gains that may be achieved from further tobacco control measures in Australia via application of PALYs, which are a novel, and readily estimable, measure of the impact of health and health risk factors on work productivity.

Exploring the utility of Analytic Hierarchy Process (AHP) in ranking livelihood activities for effective and sustainable rural development interventions in developing countries.

It is commonly known that most development projects, especially in the global south, tend to achieve unintended results or fail because of lack of due diligence. Project satisfaction and sustainability would only be achieved if consistent with the actual needs of the people intended to benefit. Based on field experiences in the Fantekwa District of Eastern Ghana, this study aims to explore the utility of the Analytic Hierarchy Process (AHP) in prioritizing livelihood activities to aid in effective and sustainable poverty reduction interventions in developing countries. Data from twenty five development stakeholders in the district were used for the assessment. The study demonstrates that with appropriate data, and systematically following all required processes, the AHP approach can effectively show where intervention is most needed. Application of AHP in the current context, the study argues, has the potential to address the issue of wrong development targeting with associated counterproductive and nonstarter outcomes.

Effect of paid work on health in opinions of Polish adolescents aged 14-15.

INTRODUCTION: The positive aspects of work of the underaged are perceived as including its economic value, positive role in the process of upbringing and socialization, and in the process of vocational training or economic education. However, on the other hand, attention is also paid to the negative consequences of work, such as threats to psychophysical and intellectual development, risk to health or even life, of the adolescents. MATERIAL AND METHODS: The basis for this study was a survey conducted in a group of Polish adolescents aged 14-15 years. The study was conducted during 2016-2017 in a representative group of 5,468 schoolchildren from junior high schools, selected by the method of stratified sampling. The research material was collected using a questionnaire for the assessment of the phenomenon of economic activity among adolescents. RESULTS: The results of the study showed that approximately 20% of Polish adolescents aged 14-15 performed paid work as hired labour, about 30% helped with running a family business (family farm, family business), and nearly 20% of respondents undertook independent economic activity. The majority of economically active adolescents are of the opinion that the work performed exerts a positive effect on their health. Evaluation of the work activities performed as dangerous, worse state of health of adolescents, and lower parameters of their physical development, exert the greatest effect on the perception of a given work as negatively affecting health. Negative evaluations of the effect of work on health also shape the perception of work as severe and experience of accident at work. CONCLUSIONS: These results may be used for the elaboration of practical recommendations in order to reduce negative effects, and enhance positive effects which work exerts on adolescents' health.

Agreement among the Productivity Components of Eight Presenteeism Tests in a Sample of Health Care Workers.

BACKGROUND: Presenteeism (reduced productivity at work) is thought to be responsible for large economic costs. Nevertheless, much of the research supporting this is based on self-report questionnaires that have not been adequately evaluated. OBJECTIVES: To examine the level of agreement among leading tests of presenteeism and to determine the inter-relationship of the two productivity subcategories, amount and quality, within the context of construct validity and method variance. METHODS: Just under 500 health care workers from an urban health area were asked to complete a questionnaire containing the productivity items from eight presenteeism instruments. The analysis included an examination of test intercorrelations, separately for amount and quality, supplemented by principal-component analyses to determine whether either construct could be described by a single factor. A multitest, multiconstruct analysis was performed on the four tests that assessed both amount and quality to test for the relative contributions of construct and method variance. RESULTS: A total of 137 questionnaires were completed. Agreement among tests was positive, but modest. Pearson r ranges were 0 to 0.64 (mean = 0.32) for Amount and 0.03 to 0.38 (mean = 0.25) for Quality. Further analysis suggested that agreement was influenced more by method variance than by the productivity constructs the tests were designed to measure. CONCLUSIONS: The results suggest that presenteeism tests do not accurately assess work performance. Given their importance in the determination of policy-relevant conclusions, attention needs to be given to test improvement in the context of criterion validity assessment.

Associations of Tipped and Untipped Service Work With Poor Mental Health in a Nationally Representative Cohort of Adolescents Followed Into Adulthood.

Precarious work is concentrated in the service industry in the United States and is a risk factor for poor mental health. Service occupations in which workers receive tips are potentially more precarious due to unstable schedule and income, and lack of benefits. We tested hypotheses that individuals working in tipped service occupations have greater odds of experiencing poor mental health (as indicated by self-reported depression, sleep problems, and/or greater perceived stress) relative to individuals in untipped service and nonservice occupations, using cross-sectional data from wave IV of the National Longitudinal Study of Adolescent to Adult Health data set (2007-2008; age range, 24-33 years). To improve comparability of occupation types, propensity scores were computed as a function of childhood factors, then used to construct a sample of 2,815 women and 2,586 men. In gender-stratified multivariable regression, women in tipped service had greater odds of reporting a depression diagnosis or symptoms relative to women in nonservice work (odds ratio = 1.61; 95% confidence interval: 1.11, 2.34). Associations of similar magnitude for sleep problems and perceived stress were observed among women but were not statistically significant; all associations were close to the null among men. Additional research is necessary to understand the factors that underlie differences in poor mental health in tipped and untipped service versus nonservice workers.

Racial variation in the effect of motherhood on women's employment: Temporary or enduring effect?

Part of the motherhood wage penalty results from mothers' loss of work experience, yet little research has investigated whether this loss is temporary or accumulates over time. Using growth curve models and data from the National Longitudinal Study of Youth (1979), I examine the extent to which motherhood reduces work experience over the life course among White, Black, and Hispanic women. Results indicate that motherhood slows the accretion of experience in full-time work for all racial-ethnic groups, having an enduring effect on women's employment. The effect is stronger among Whites and mothers with two or more children, remaining sizeable as women approach retirement age. By age 50, White and Hispanic mothers with two or more children exhibit between two to seven fewer years of experience in full-time employment. Among Blacks, only mothers with three or more children experience a significant reduction, averaging five fewer years of experience in full-time work.
