What should I know about clearly communicating part-time work, bridging part-time and working hour models?

In Germany, weekly hours, hour corridors, part-time options and where applicable return-to-full-time logic should be listed separately. Recommendation: do not use part-time as a simple yes/no flag, but link it to concrete hour logic. In practice: display weekly hours as a number or corridor rather than just full-time/part-time. Limitation: not every role can be described with narrow hour corridors. (Sources: Destatis Labour Market, BA Beschaeftigung Statistik)
