What should I know about working time, overtime, and availability before contract acceptance?

Germany should represent working time model, core hours, shift/night work proportion, and overtime logic as separate fields. Recommendation: do not hide information about on-call duty, standby service, or permanent availability in free text. In practice: job listing: display weekly hours and overtime rules separately. Limitation: not every operational flexibility can be fully standardised. (Sources: Destatis Labour Market, BA Beschaeftigung Statistik)
