PurposeTo investigate (a) differences in work characteristics and (b) determinants of job satisfaction among employees in different age groups.MethodsA cross-sectional questionnaire was filled in by 1,112 university employees, classified into four age groups. (a) Work characteristics were analysed with ANOVA while adjusting for sex and job classification. (b) Job satisfaction was regressed against job demands and job resources adapted from the Job Demands-Resources model.ResultsStatistically significant differences concerning work characteristics between age groups are present, but rather small. Regression analyses revealed that negative association of the job demands workload and conflicts at work with job satisfaction faded by adding job resources. Job resources were most correlated with more job satisfaction, especially more skill discretion and more relations with colleagues.ConclusionsSkill discretion and relations with colleagues are major determinants of job satisfaction. However, attention should also be given to conflicts at work, support from supervisor and opportunities for further education, because the mean scores of these work characteristics were disappointing in almost all age groups. The latter two characteristics were found to be associated significantly to job satisfaction in older workers.
CIWs take two to three times more and longer sick leave than NCIWs. Health-related aspects are more strongly associated with sick leave than work-related aspects for both CIWs and NCIWs. Sick leave patterns were, nevertheless, only partly explained by health-related and work-related aspects. In any case, future studies of sick leave should certainly take the presence of chronic disease into account as an important determinant of sick leave.
ObjectivesTo investigate differences in associations between sick leave and aspects of
health, psychosocial workload, family life and work–family interference
between four age groups (<36, 36–45, 46–55 and
55+ years).DesignA cross-sectional study; a questionnaire was sent to the home addresses of all
employees of a university.SettingA Dutch university.Participants1843 employees returned the questionnaire (net response: 49.1%). The age
distribution was as follows: <36: 32%; 36–45: 26%; 46–55: 27%
and 55+: 12%.Primary outcomesFrequent sick leave (FSL, ≥3 times in the past 12 months) and
prolonged sick leave (PSL, >2 weeks in total in the past
12 months). Differences between the age groups in independent variables and
outcomes were investigated. Logistic regression analysis was used to calculate
associations between various variables and the sick leave outcomes. Interaction
terms were included to detect differences between the age groups.ResultsAge differences were found for many work- and family-related characteristics but
not in the mean scores for health-related aspects. Presence of chronic disease was
reported more frequently with increasing age. The 55+ age group had almost
two times less chance of FSL, but 1.6 times more chance of PSL than the <36
age group. Age moderates the associations between career opportunities,
partner's contribution in domestic tasks and sex, and FSL. Job security and
pay, support from supervisor, challenging work and being breadwinner have
different associations with PSL. However, life events in private lives and
perceived health complaints are important in all age groups. FSL and PSL have some
determinants in common, but there are differences between the outcomes as
well.ConclusionsAge should be treated as a variable of interest instead of a control variable.
Employers and occupational physicians need to be aware that each phase in life has
specific difficulties that can lead to FSL and PSL.
CIWs perceived more fatigue, emotional exhaustion and health complaints than NCIWs. There were different patterns of associations between work- and health-related characteristics in the NCIWs and CIWs. Future studies on associations between work-related characteristics and health should take the presence of chronic disease into account.
Demographic changes increase the importance to stimulate working longer. Using questionnaire data, we investigated the relationship between work characteristics, job dissatisfaction and need for recovery in four age groups. Although the moderating effect of age group was rather limited, the salience of specific work characteristics within the age groups varied.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
