When I was at Amazon, the newly hired team lead was incompetent and insecure, so this person ruled the team by fear - PIP'ed people trigger happy (myself included). HR did nothing, even though this was a recurring behavior even after I left. It was just flagged, that is not possible to PIP people without actual prior performance issues and informal conversations to address them. Fast forward to today - the person is still there and eventually was promoted. In EU, where labour laws are much stronger it's not as effective, but it's pretty much a one way ticket.
