The European Working Conditions Survey (EWCS) is the longest running survey; and has become an established source of information about working conditions and the quality of work and employment. With five waves having been implemented since 1990; it enables monitoring of long-term trends in working conditions in Europe. Themes covered include employment status; working time arrangements; work organisation; learning and training; physical and psychosocial risk factors; health and safety; worker participation; work-life balance; earnings and financial security; as well as work and health.
