COVID-19 and the labour market: What are the working conditions in critical jobs?

The COVID-19 pandemic has focused public attention on occupational groups that ensure the maintenance of critical infrastructure, provision of medical care and supply of essential goods. This paper examines the working conditions in critical jobs based on representative data from the German BAuA Working Time Survey 2019. Our analyses reveal that essential workers are more likely to perform unskilled or semiskilled activities and work in cleaning, transport and logistics, health care occupations as well as IT and natural science services. Regarding the working conditions, essential workers are paid comparatively less and are more physically proximate to others at work than nonessential workers. They more often work atypical hours, such as day and night shifts and on weekends, and have less autonomy in their working time. Additionally, critical jobs are characterised by muscular and skeletal strain due to working positions and carrying heavy loads significantly more often. Thus, our findings strongly suggest that work-related risks accumulate in critical jobs.

Cumulative disadvantage during employment careers - The link between employment histories and stressful working conditions

Accumulated evidence on health-adverse effects of stressful psychosocial and physical work environments is considered a major breakthrough in recent social epidemiological research. However, research on adverse health effects of repeated exposure over time is lacking. In this contribution we analyse associations of characteristics of adverse employment histories with stressful psychosocial and physical current working conditions. We use data from the French CONSTANCES study and restrict the sample to employed men and women aged 45-60 (n = 23652). Current working conditions are assessed by effort-reward imbalance as well as stressful physical working tasks and positions. Previous employment histories (between age 25 and 45) are retrospectively assessed and measured by indicators of precarious, discontinuous and disadvantaged working careers. We found consistent associations of precarious, discontinuous or disadvantaged careers with strenuous physical working conditions and with low occupational rewards. However, low effort rather than high effort was associated with adverse employment histories. Therefore, associations with the effort-reward ratio turned out to be inconsistent. By extending the scope of analysis beyond single time-point measures, we identified three types of adverse employment histories among employees between age 25 and 45 in a stress-theoretical framework, and we demonstrated their associations with employees' current adversity at work between the age of 45-60.

Physical and psychosocial work factors as explanations for social inequalities in self-rated health

OBJECTIVE

We investigated the contribution of physical and psychosocial work factors to social inequalities in self-rated health (SRH) in a sample of Danish 40 and 50 years old occupationally active women and men.

METHODS

In this longitudinal study, the study population consisted of 3338 Danish women and men. Data were collected by postal questionnaires in 2000 (baseline) and 2006 (follow-up). The independent variable, socioeconomic position (SEP), was assessed by the highest achieved educational level at baseline. We conducted gender-stratified parallel multiple mediation analyses. In the mediation analyses, SEP was categorised as SEP I, II, III, VI and V among men. Among women, SEP was dichotomised into SEP I-IV and V. The outcome, SRH, was assessed at baseline and follow-up. A wide range of physical and psychosocial work factors were included as potential mediators.

RESULTS

We found a social gradient in SRH across all levels of SEP among men. Among women, we only found a poorer SRH among those with the lowest SEP. Mediation analyses showed that work factors together accounted for 56% of the social inequalities in SRH among men and 44% among women. In both genders, ergonomic exposures and job insecurity seemed to play the major role for social inequalities in SRH. For women only, we also found noise to contribute to the social inequalities in SRH.

CONCLUSION

Physical and psychosocial work factors partially explained social inequalities in SRH among both genders. Improvement of the working environment can potentially contribute to the reduction of social inequalities in health.

Working conditions mediate the association between social class and physical function in older age in Sweden: a prospective cohort study

Background

Global demographics are changing as societies all over the world are aging. This puts focus on maintaining functional ability and independence into older age. Individuals from lower social classes are at greater risk of developing limitations in physical function later in life. In this study, we investigated the mediating role of working conditions in the association between occupation-based social class and physical function measured as self-reported mobility limitations and objectively measured physical impairment in older age.

Methods

Two Swedish surveys, linked at the individual level, were used (n = 676–814 depending on the outcome). Follow-up time was 20–24 years. Multiple logistic regression analyses were performed with adjustments for age, sex, level of education, mobility, and health problems at baseline. This was followed by analyses of the size of the mediating effect of working conditions.

Results

Working conditions seem to mediate 35–74% of the association between social class and physical impairment in older age. The pattern of mediation was primarily driven by passive jobs, i.e., low psychological demands and low control, among blue-collar workers. Working conditions did not mediate the association between social class and self-reported mobility limitations in older age.

Conclusions

The results of this study indicate that working conditions are important in combating the social gradient in healthy aging, contributing to the evidence regarding the magnitude of impact exerted by both the physical and psychosocial work environment separately and in conjunction.
