Usually, labour market has been evaluated from a quantitative point of view. But nowadays, a new interest stress on quality of job and job satisfaction. Related with this last perspective, a frequent hypothesis that is used to explain the aggregate evolution of job quality establish that the growth of service employment is connected with the increase in the number of low skilled or badly paid jobs. Nevertheless, defining and understanding service jobs are tasks that are not free of difficulties. Recent developments in the economic analysis of service activities overcome these shortcomings, and the nature of these activities has been re-invented. In this context, the paper aims a double objective. First, to check if job quality levels on services are lower than the ones observed in the rest of the economy. Second, to know if relevant differences among services activities exist in term of job quality. Our analysis uses a double perspective to measure the job quality: one based on the characteristics of job and the other on workers perception of job. Results point out that services have not the lower quality job levels. On the contrary, workers in services activities report higher job satisfaction levels. We conclude that into services there is an important heterogeneity by branches in terms of job quality. Services and no services share job satisfaction components. So, the observed differences in job satisfaction are sustained rather on differences into the characteristics and conditions of jobs more than into worker perceptions.JEL codes: J28, J24, J81
