Also, if you have children you have priority during school breaks for paied leaves.

This surprises me actually, it seems to have a built-in discrimination from the outset.

I've got little PhobosAnomalies at home, and my jobs over the years have taken me all over the place so school holidays haven't been a priority for me. That said, I wouldn't personally consider my need to have a week or two off in the school holidays or summer holidays as a priority, more just the same importance of everyone else. After all, having little'uns is mostly a choice (or sometimes, the choice isn't even available 😢) so it seems like a world of employment law hurt to grant the parents a higher level of priority than others.

That said, I ain't in Germany so it's a moot point really.
