This report analyses the implications that new forms of work organization have for different aspects of conditions of employment, such as hours of work, the intensification of work and health at the workplace, pay systems, security of employment, work and family, and social dialogue. The organization of work has great implications for the quality of working life, and this is clearly demonstrated by the ongoing debates on changes in work organization in the direction of greater flexibility and their potential and actual effects on workers. While it is widely assumed that flexible forms of work organization can have desirable influences on both the enterprise and its workers, these outcomes are often not realized in practice. Even when a new form of work organization results in positive outcomes overall, the gain is not always shared by all the participants involved: in many cases, some workers benefit from the change, but others do not.
