Flexibility of working hours and social inequalities
In 1999, the traditional working day (9am-5pm) accounted for a small majority of the days actually worked. Over the last 15 years, three new patterns of working hours have emerged: shift work, longer working days and split shifts. Such irregular working hours often go hand in hand with disadvantaged social situations. Employees with the freedom of choice clearly prefer standard working hours; consequently, irregular working hours are most often imposed rather than chosen.
