Severance money impact if legal action taken against company for unfair termination in Europe.

Are you eligible for severance money, if you decide to take legal action against the company for unfair termination? In my case it's not termination, but an option to take better severance and leave Amazon, and not go into PIP. But the reason to put into PIP is unfair, with several proofs. What would you suggest? Can you take legal action for putting into PIP that too unfair? #amazon #pip #amazonpip #aws #amazonfocus #amazonaws #amazonbenefits
