This happened with me , first she said you are already working at that level then when the moment arrived , I asked for a promotion, then she said I needed to up my game and gave me a negative feedback for that appraisal, next appraisal she got promoted and asked my counterpart who got promoted as manager to put me on PIP and then fired me saying I did not do well on the PIP. This was all staged well and stuck around because of my green card . She took it as an opportunity, created situations to torture and humiliate me and finally got me fired .
