In Poland in some areas of the government owned energy/coal mining sectors there are/were actual 'employment inheritance' clauses in place to let candidates from families of current or past workers get employment before unrelated ones. There were attempts to get rid of them but that caused union protests and strikes and some unions want more of these so I have no idea what's the current situation is. Some analysts say they are dead clauses though (due to national labor laws which forbid any discrimination taking precedence) and only in there to make unions content and not strike or protest.
