Dear Sir, I am a serving confirmed employee of a Pvt sector Bank I have been issued PIP in the month of October from my manager after that when I saw I would be not able to achieve the targets given I put down my papers in November and currently serving notice. In the first PIP letter, it is clearly mentioned that there will be 3 PIP's if my performance doesn't improve. when I put down my papers my resignation was approved by my manager and HR but in my notice period after they are issuing me 2nd PIP and 3 PIP and threatening to terminate me and also asked me that they will not issue a relieving letter.
