After going through the entire issue, now you have undergone 2 appraisal cycle though you have been rated & given good feedback, no increment has been given which is flaw. Now you are put down to PIP without any proper communication of why & what for? which is a flaw again. So it is clear that no professionalism prevailing in your team. It is merely on personal ego's the manager is doing what he want. Any PIP should be communicated to HR. HR should be in loop for all such communications. You should approach your HR & state the matter.There is always scope for you to highlight the emails which you have addressed regarding your work pressure and allotment.
Another query I have is if I resign after PIP is accepted ( Right now manager is waiting for my acceptance on it ) , in the PIP period of 60 days if I resign would it harm me in any case with respect to my full n final and My salary ? Would they be deducting any salary stating that PIP is still in place or something like that ?
Thanking you in anticipation
As i gone through and understand your concern... if you really performaing bad and have been put under PIP, this is should be intimated or copied to HR must. I would suggest if you can reach to HR that may give you some better result.
You can bring up the following to HR to get him educated on your query.
1. Show the written mail which you have been informed that you have met expectations regarding performance.
2. If your reporting really found gaps on your performance he should show the proof for the same as a record.
3. Although the worrest part was HR haven,t been informed regarding the case, which ignores him/her out of the box.
All the best.
