First, note that in the analyses including job insecurity as an additional covariate to age, the effect of age on contract differences in emotional exhaustion became non-significant. Secondly, the quality of working life hardly reduced the contract differences in health, as the F-values controlled for the quality of working ALK inhibitor life and age (Table 3)
were similar to the F-values only controlled for age (Hypothesis 5a not supported). Furthermore, the expected reduction due to job insecurity was only supported for musculoskeletal symptoms, while the F-values for general health and emotional exhaustion increased (Hypothesis 5b partially supported). Finally, the contract differences in health could not for the largest part be explained when controlling for both the quality of working life and job insecurity (Hypothesis 5c not supported). Contract differences in work-related attitudes explained Hypothesis 6 consists of three subhypotheses. First, we expected the quality of working life to partly explain contract differences in work-related attitudes (6a). Indeed, see more as shown in Table 4, the quality of working life reduced most (i.e. 2 out of 3) F-values for these contract differences (namely those
for work
satisfaction and employability), but the F-value for turnover intention increased (Hypothesis 6a partially supported). Secondly, all F-values for the contract differences in work-related attitudes, especially those for work satisfaction and turnover intention, decreased when controlling for job insecurity (Hypothesis 6b supported). Finally, most (i.e. 2 out of 3) F-values in Table 4 (namely those for work satisfaction and employability) were reduced most when controlling for both the quality of working life and job insecurity (Hypothesis 6c thus partially supported). Discussion Temporary work is on the increase in the European G protein-coupled receptor kinase Union, and there is some concern as regards the quality of working life, job insecurity, health and well-being of these temporal employees. In a large and representative sample of the Dutch working population, we first AZD1480 manufacturer investigated contract differences in the quality of working life, job insecurity, health and work-related attitudes. Secondly, we investigated the role of the quality of working life and job insecurity in the relation between different employment contracts and health and work-related attitudes. Table 5 summarises the support for each of our hypotheses.
