Drawing on effort-recovery theory, author expected that high job demands, low job control, a high number of hours worked overtime, and a full-time appointment would be associated with high levels of work-home interference, low levels of enjoyment, and high levels of exhaustion. By including both negative (exhaustion, work-home interference) and positive (work enjoyment) indicators of worker well-being, author explore whether the effects of effort expenditure and lack of recovery are similar for different facets of well-being. In this chapter, the author asks whether the effects of indicators of effort expenditure and internal versus external recovery opportunities relate in a similar fashion to positive and negative indicators of worker well-being. All females and half of the males in the six highest salary scales (starting at 45,000 euros a year gross) received a questionnaire addressing background variables, work characteristics, subjective well-being, work-home interference, and overtime.
