Time-based and strain-based work-family conflict in the South African police service: examining the relationship with work characteristics and exhaustion
MetadataShow full item record
The objectives of this study were 1) to investigate the relationship between work characteristics, work-family conflict (WFC) and exhaustion, and 2) to determine whether time-based and strain-based WFC mediate the relationship between different work characteristics and exhaustion. A random sample was taken of 224 inspectors in the South African Police Service in the North West Province. It was hypothesised that 1) work characteristics are related to time-based WFC, strain-based WFC and exhaustion, 2) time-based and strain-based WFC are related to exhaustion, and 3) time-based and strain-based WFC partially mediate the relationship between work characteristics and exhaustion. Multiple regression analyses were used to test these hypotheses. The results showed that overload, organisational support, growth opportunities and contact possibilities with colleagues were related to both types of WFC and to exhaustion. Time-based and strain-based WFC were also related to exhaustion. In the regression analyses, all the work characteristics and both types of WFC contributed significantly to exhaustion levels. None of the WFC types mediated between overload, organisational support, growth opportunities and exhaustion. However, a full mediating effect of both time-based and strain-base WFC was evident between contact possibilities with colleagues and exhaustion.
