Organisational and relational factors that influence return to work and job retention: The contribution of activity ergonomics.

BACKGROUND: Work is a determinant of employee health, and the same conditions that contribute to an illness do not favour return to work; consequently, they hinder job retention, other employees can become ill and new leaves are generated. OBJECTIVE: To analyse the nursing technicians work in intensive and semi-intensive care units (ICUs and SICUs) and discuss the influence of organisational and relational factors on return to work and job retention. This study also discusses the contributions of activity ergonomics to these processes. METHOD: Qualitative case study based on ergonomic work analysis (EWA). Data were collected using documentary analyses, and global, systematic, and participant observations involving nursing technicians working in ICUs and SICUs. RESULTS: Task planning and the staff size adjustment to respond to the work demands of these units were ineffective in real-world situations and were aggravated by cases of absenteeism, medical leave, and employees returning to work. CONCLUSIONS: Work structure limits return to work and job retention. An EWA based on the activities developed by professionals is a valid tool for understanding working processes by applying transforming actions to real-world work situations.

Defining the meaning of "sustainable work" from activity-centered ergonomics and psychodynamics of Work's perspectives.

INTRODUCTION: Work-related issues are already part of the theoretical framework and the historical rationale that underpin corporate sustainability. However, the relationship between work and sustainability is still little known in company practices. Based on the concepts of activity-centered ergonomics (ACE) and psychodynamics of work (PDW), this paper investigates the meaning of "sustainable work" in Brazilian companies. Thus, two research questions guided this study: How the concept of "sustainable work" can be defined in the perception of companies based on the perspective of ACE and PDW? How the concepts provided by these approaches can help companies in developing practices towards sustainable work? METHOD: Case studies conducted in ten Brazilian companies engaged in corporate sustainability practices involving document analysis, interviews, and content analysis. RESULTS: Companies recognize the importance of human action in organizational processes, by considering people as the cornerstone for ensuring corporate sustainability, and seeking to build a work with meaning and significance. However, i) Improvement actions are usually mitigatory or compensatory, acting on the effects while the root causes remain untouched; ii) Sustainability initiatives focus on individual issues, in most cases on the leader (individual), narrowing its scope and neglecting broader, important topics such as work organization and work content; iii) Both work overload and work for sustainability agenda are usually disregarded; iv) A comprehensive view of health should not be limited to the workplace. CONCLUSIONS: According to companies' perceptions, sustainable work includes but is not limited to integrating work to corporate sustainability guidelines, respecting labor laws and human rights, developing synergy between areas/departments towards sustainability, providing possibilities for constructing health in its multidimensionality with the worker as protagonist, and creating work that is meaningful, pleasurable and leads to happiness and recognition. ACE and PDW offer valuable concepts to support companies in bridging the gap between their corporate sustainability vision and practices, i.e., transforming guidelines into actions towards sustainable work. In this sense, sustainable work is believed to be that which improves the organization's performance and promotes professional development as well as workers' health broadly and positively (not limited to the absence of illness, but in the sense of building health) and well-being. Thus, it fosters respect for and the development of intelligence and creativity (as opposed to alienating work) by performing work that has meaning and significance, understanding the profound importance of physical, cognitive and organizational issues, and above all, the importance of work to the development of culture (Bolis et al., 2014).

Brumadinho: entre a prudência e a probabilidade, a tragédia / Brumadinho: between prudence and probability, tragedy

Será possível, em algum momento no futuro, explicar com exatidão o que aconteceu no caso do rompimento da barragem de Brumadinho? Apesar de, muitas vezes, se utilizar a palavra exatidão no mundo da engenharia, sabe-se que, em muitos casos, trata-se de um eufemismo. A arte da engenharia consiste em projetar, construir, implementar e gerenciar diferentes tipos de sistemas que podem trazer consequências tanto positivas como negativas para os trabalhadores, para a sociedade, para o meio ambiente. Aconteceu um evento ou uma sequência de eventos que levou ao rompimento. A engenharia de barragens de rejeitos conhece e é capaz de controlar todos os eventos passiveis de acontecer e que, articulados, podem levar ao rompimento? Há dois caminhos: primeiro, o conhecimento total; a engenharia conheceria tudo e seria capaz de projetar de modo a evitar, com certeza, todos os eventos nocivos. Segundo: a engenharia não conhece a totalidade dos fenômenos, mas sabe que, fazendo como sempre se fez (com o conhecimento empírico) e com margens de segurança grandes, a probabilidade de rompimento se aproxima de zero. Ninguém projeta uma barragem para que ela se rompa. Mas se projeta uma barragem sem dominar na totalidade os eventos que podem ocorrer. Quando se conhece a totalidade da situação, o que deve ser feito para evitar o rompimento é 100% conhecido ­ e precificado. Entretanto, isso nunca acontece, a probabilidade de ocorrência de eventos nunca é completamente conhecida, eles não são determinísticos e a incerteza é um fato.

Will it be possible, sometime in the future, to exactly explain what happened in the dam failure in Brumadinho? Although word "exactness" is often used within the world of engineering, it is often known to be an euphemism. The engineering art consists in projecting, building, implementing and managing different types of systems which might have both positive and negative consequences for workers, society and the environment. Some event or series of events culminated in the dam failure. Is tailings dam engineering aware of and able to control all possible events which together might cause a failure? There are two possible paths: one involves absolute knowledge ­ engineering has absolute knowledge of everything and is able to design projects in a way to avoid any harmful event. According to the other, while engineering does not have absolute knowledge of all the phenomena, its traditional know-how (empirical knowledge) and wide margins of safety make the odds of dam failure come close to zero. No one projects a dam just to fail. But dams are projected without absolute control of all possible events. When the entire situation is known, all that should be done to avoid failures is 100% known ­ and the price fixed. However, this never happens, the probability of the occurence of events are never completely known, they are not deterministic and uncertainty is always a fact.

Work for sustainability: Case studies of Brazilian companies.

The introduction of strategic corporate sustainability policies is expected to result in the improvement of several issues in companies. One of these issues is work, which should involve greater well-being for workers. Within the context of production engineering, this research connects sustainability and work-related issues, the latter seen in light of the discipline of ergonomics. Based on case studies conducted at four companies considered sustainability benchmarks, we examined how the introduction of the theme of sustainability has influenced work-related issues. The elements analyzed here were the corporate sustainability strategy, organizational practices for deploying the strategy, and the work design phase. The last element is the moment in which work is prescribed in the organization. The results show that, despite the announcement of the inclusion of changes in work, there is not any explicit evidence confirming that such changes are considered as a requirement for corporate sustainability projects.

Mapping the relationships between work and sustainability and the opportunities for ergonomic action.

A map was drawn up of the relationships between work (in its multiple interpretations) and sustainability (sustainable development and corporate sustainability) based on a bibliographic analysis of articles that discuss these themes jointly in the current academic literature. The position of the discipline of ergonomics focused on work was identified from this map and, based on its specific academic literature, it was possible to identify where this discipline could contribute so that work and workers can be included in the discourse of sustainable development and considered in corporate sustainability policies. Ergonomics can be actively influential within the organization on issues relating to work improvements; it may boost integrated increases in the organization's performance and in workers' well-being; it can provide support for changes and new (environmental) sustainability-related work requirements to be considered; and it can contribute to the definition of the concept of work in a context of sustainable development.

Contributions of ergonomics to the construction of bus drivers health and excellence in public transport and at work.

This article is the product of research that analyzed the work of bus drivers of a public transportation company that is considered a benchmark reference in its field of operations, in which it strives to achieve operating excellence. Within this context, the authors sought to understand how such a company has managed to maintain a policy that is capable of reconciling quality public transport while also providing working conditions compatible with the professional development, comfort and health of its workers. Ergonomic work analysis and activity analysis were the guiding elements used in this study. Initial analyses indicate that the activity of drivers includes serving a population and providing mobility for it, which depends on driving the vehicle itself and on relationships with colleagues, users, pedestrians, drivers and others.

The workers role in knowledge management and sustainability policies.

Based on the concepts of sustainability and knowledge management, this article seeks to identify points of contact between the two themes through an exploratory study of existing literature. The first objective is to find, in international literature, the largest number of papers jointly related to the theme of knowledge management and sustainability. In these documents, the authors looked at the kind of relationship existing between the two themes and what the benefits introduced in organizations are. Based on an ergonomic point of view, the second objective of this article is to analyze the role of the worker (whether at the strategic or operational level) and his importance in this context. The results demonstrate that there is very little literature that addresses the two themes together. The few papers found, however, can be said to show the many advantages of introducing sustainability policies supported by adequate knowledge management. Very little has been studied with regards to the role of workers, which could be interpreted as meaning that little importance is given to the proactive role they may play. On the other hand, there is a high potential for future research in these areas, based on the high level of consideration of workers in knowledge management and sustainability literature, as well as in literature in the areas of ergonomics and sociology.

Involvement and emancipation of the worker. Action research in a university hospital.

The present action research article is linked to an ergonomics project in a university hospital. The author's proposal is to focus action on the effective worker involvement required for the creation of spaces/mechanisms within organizations where people can enhance cooperation and deliberation on matters relating to work. For this purpose, a committee was introduced to assist in finding problems and solutions directly in work situations, so that workers could experience relative autonomy allowing them to develop procedures and choose tools appropriate to their own real needs. Based on this organizational implementation and on subsequent interviews, the practical results are analyzed and related to employee involvement. One can conclude that workers in all areas of the organization can be active elements for improving working conditions and productivity in companies.
