The purpose of this paper is to compare the extent and determinants of employees’ job satisfaction on a European level. The underlying data originate from the European Working Conditions Survey (EWCS) 2005 covering 31 European countries. Beside detailed information about type of work and working conditions the data account for personal and household characteristics including objective and subjective income measures. The result from Ordered-probit regressions for all 31 countries as well as separate regressions for five groups of countries (clustered with respect to level of welfare and type of welfare state) indicate a diversified pattern of explanation of job satisfaction. For all analyzed countries except for countries in Scandinavia and continental Europe the employees’ subjective evaluation of income appears to have the strongest effect on job satisfaction. Considering the conflict of working hours with private life, the negative effect on job satisfaction is less distinctive in countries with a lower welfare level. Job security is found to have a stronger impact for UK and Ireland, whereas work autonomy is only found to be among the top ten influences for high level welfare states (UK, Ireland, continental Europe, and Scandinavia).
