Age as a moderator in the relationship between work-related characteristics, job dissatisfaction and need for recovery

Abstract

Job dissatisfaction and need for recovery are associated with voluntary turnover, absenteeism and diminished health. In the light of encouraging working longer, this study investigated whether the relationships between various work characteristics and job dissatisfaction and need for recovery are dependent on age. Cross-sectional questionnaire data from 591 university employees were divided into four age groups: < 36, 36–44, 45–54 and ≥ 55 years. Multivariate regression analyses were used, including interaction variables to detect a moderating effect of age group. Limited age group effects were found: only the association of Feedback with job dissatisfaction and Task variety with need for recovery were influenced by age group. The salience of specific work characteristics within the age groups varied: for job dissatisfaction, Task variety ( < 55) and Changes in tasks ( ≥ 55) were most important. For need for recovery, this applied to Autonomy ( < 36) and Workload ( ≥ 45). To encourage working longer, age-specific measures could be considered, in addition to individual measures, to respond to individual needs.

Practitioner summary: 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.
