2. A I A S 2 Employer driven overtime extended hours mostly employer-driven (Peetz, AUS, 2003) unemployment rates decrease overtime; current level of production increase overtime, yet not the expected level (Kraft, GER, 1989) firm size positively related to overtime (Duchesne, CAN, 1997)

3. A I A S 3 Employee-driven overtime interactions of private and on-the-job use of computers increase unpaid overtime (Hubler, GER, 2000) workplace culture important; employees internalise overtime pressure (Peetz, AUS, 2003) skilled workers more overtime than unskilled (Bauer and Zimmerman, GER, 1999)

A I A S 4 Who has overtime hours men more overtime than women; 15-24 yrs & low-skilled more paid overtime; 45-54 yrs & skilled more unpaid overtime: little overtime for lone parents (Duchesne, CAN, 1997) men + newcomers work overtime, leavers don’t (Bockerman, FIN, 2002) empirical evidence to what extent overtime is employer- or employee-driven is lacking
