Without going into too much detail, my manager was 'mobbed' by their director to a point where the director spread false rumors about them (found out about this from several people high up in the reporting chain) and the manager was forced to switch teams. I was appalled at the power directors can wield and the power disparity, the lack of transperency (and at the fact that the other people higher up in the reporting chain were not willing to or able to stand up for them even though they knew the rumors were fabricated)
Now a close friend is going through something similar at a FAANG company being seemingly targeted by their director pushed to leave a team they have been happy and effective (high performance ratings) on for years.
Especially wondering if there is any director, VP level people here who could shed light on how common this is and how accepted it is at your company? What are your options when this happens to you?
