During WW2, when armies advancing through enemy territory captured enemy factories / oil refineries, how did this actually work in practice?

Forgotten Weapons has videos about many guns that were made under occupation.

I unfortunately can’t remember any specifics, but I can say that it was a spectrum between forced labour and just getting paid to do the same work by someone else.

Depending on who invaded.
