How do I implement clear communication of part-time work, bridging part-time and working hour models in practice?

In Germany, weekly hours, hour corridors, part-time options and where applicable return-to-full-time logic should be listed separately. Display weekly hours as a number or corridor rather than just full-time/part-time. Part-time options with minimum and maximum ranges. Note: not every role can be described with narrow hour corridors.
