Book excerpt: Monograph No. 6, revised and updated, presents the norms of the European Social Charter of 1961 and the case law of the European Committee of Social Rights in relation to conditions of employment : the right to health and safety at work, which includes length of working hours and holidays as well as industrial safety and health, and the right to a decent standard of living, guaranteed for workers and their families by ensuring adequate remuneration.This study demonstrates how the Committee's case law has allowed the Charter's norms to adapt to important developments in these matters, and in particular those concerning the flexibility of working hours. It also highlights the improvements introduced by the revised Charter of 1996 in the area of health and safety at work.
