Highlights

  • The Job Demand-Control model is used to understand origins of work-related stress.

  • A longitudinal Australian sample (HILDA; 2005–2013) is analyzed.

  • The self-employed report significantly less work-related stress than wage workers.

  • Job control fully mediates the relationship between self-employment and stress.

  • The self-employed with employees report more stress than those without employees.

Abstract

Drawing upon the Job Demand-Control (JDC) model, this study investigates differences in work-related stress between the self-employed and wage workers. The JDC model postulates that job demand increases work-related stress, whereas job control reduces it (also by weakening the effect of job demand on work-related stress). Based on this model, we predict that the self-employed experience less work-related stress than wage workers. Empirical analysis of a longitudinal sample from Australia (2005–2013) confirms our expectations and demonstrates that job control fully mediates the negative relationship between self-employment and work-related stress. Further analyses show that self-employed individuals with employees experience more work-related stress than those without employees because of higher job demand.

Executive summary

People experience stress from work when the requirements of their jobs exceed their mental and physical resources and are perceived as threatening or even harmful. Stress from work could not only deteriorate performance at work but may also adversely affect health status and well-being in general. Moreover, the societal costs (e.g., health-care costs and loss of productivity) of work-related stress are substantial. To reduce these personal and societal costs, it is important to gain insight

Stress

Stress “refers to a relationship between the person and the environment where the requirements of the situation exceed the person's resources and are appraised (by him or her) as involving harm, a threat of harm, or a challenge” (Shepherd and Patzelt, 2015, p. 23). The body reacts to stress by producing more energy and strength to overcome the challenge and by curbing bodily functions that are nonessential in a threatening situation (APA, 2016b). Therefore, stress can help individuals to reach

Sample

Our analysis draws on data from the Household, Income and Labour Dynamics in Australia (HILDA) survey. The HILDA is a household-based longitudinal survey that has been in existence since 2001 and contains data about many work-related characteristics. Since the fifth wave (2005–2013), the HILDA survey has included two work-related stress measures, three job demand measures, and three decision authority (job control) measures (see below). The response rate of the waves under investigation is

Summary statistics

Descriptive statistics – means and standard deviations – are presented in Table 2 for individuals in wage work (N = 62,488) and in self-employment (N = 5776) and for the self-employed with (N = 1445) and without employees (N = 4331). Job control and job demand are standardized to enhance the comparability of the estimated coefficients and indirect effects of both variables at a later stage.

We observe in Table 2 that work-related stress is on average lower for the self-employed (2.60) than for wage

Discussion and conclusion

Experiencing work-related stress could have severe consequences for individuals and societies, and understanding its causes is of utmost importance. The literature on self-employment and stress is, however, scarce and has provided mixed results. Our theoretical model predicts and empirical findings show that the self-employed without employees experience significantly less work-related stress than wage workers and that the self-employed with employees experience significantly more stress than
