If you are HR Executive in BPO, then you must be reporting to some senior HR. Did you discuss your problem with your reporting authority from HR? If yes, what was his/her take?
If your performance was not up to the mark then why AVP (Ops) gave this feedback to you? Why not your HOD?
Since we do not know the internal dynamics of the company, it will be difficult for us to give our opinions. Secondly, have you given your formal letter of resignation? If yes, then are you on notice period? Instead of quitting company, was option of change of department available to you? If yes, then why you did not avail of that?
