Trending @Accenture; PIP and Notice period issue

Hi Everyone, yesterday I got to know that my manager is putting in PIP. Even though my performance is good but since my mother died in 1 months back he makes an excuse that I am not working properly and depends on others.

Due to this I Resign from the company so that at least I can serve 90 day to help financial.

I just wanted to know if I'm on notice period can they put me in PIP.

And if they roll off me from the project will my notice period get reduced?

I am an associate but the manager makiny my life hard even in this situation. Please suggest
