We estimate an ordinal logistic multilevel model to examine the determinants of the life satisfaction of employees in Europe. Data drawn from the European social survey reveals that deviations from desired hours of work (measured as the absolute difference between the actual and preferred weekly number of hours) reduce overall life satisfaction, but the effect is smaller in countries with higher unemployment rates. We interpret this finding as evidence that in environments where anxieties about job security are high, having a job brings about a certain level of life satisfaction regardless of the gap between the actual and preferred time spent in the labor market. We also find no statistically significant difference between male and female employees with regard to the impact of the work hours mismatch. This finding suggests that the gender differences which would have been expected in this context are already incorporated in the respondents’ subjectively determined desired hours of work. In fact, further examinations confirm that ‘desired hours’ are associated with both socio-demographic characteristics (in particular, gender) and preferences for labor market work.
