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?
1) business bureaucracy is, in truth, more or less like the inside of the old Soviet bureaucracy and Politburo, except instead of getting killed or imprisoned you get fired. There is no guarantee of fairness or rationality.
2) this sort of thing happens more often if it's a "shrinking pond", where people start to think that somebody's going to get laid off, so they need to start discrediting somebody else so it won't be them. In good times, everybody has more work that needs doing than they have people to do it, and they behave differently (typically).
3) it is never easy to get a different job, and especially not in tech right now, but it's harder when you don't have one; you should start looking now.
But to steal a line from the Mel Gibson movie where he had blue paint on his face:
"The Lord tells me he can get me out of this mess, but he's pretty sure you're foocked."
But even in the US part of the company, it should be hard for it to play out, but probably a lot easier: while most people, including other directors, seem to be good human beings, we are all stretched extremely thin and I am sure someone could easily get something to slip past us.
TBH, I am always surprised how do people get into situations like this and what are the types of people that do this? Like what do they gain from it? How far it takes them? I know I am naive and I have seen my fair of shit over ~20 years in the industry, but it still boggles my mind.
On the other side of it, I am sure one person — they under-performed but thought extremely high about themselves and got frustrated when I disagreed — would have claimed they were being mobbed by me (even after attempting to get improvements from them for 6+ months). So since you are not in your close-friend's shoes, do take note that they might not be sharing the full story and they are certainly not 100% objective either.
But for anyone having these sorts of disagreements with me, I advise reaching out to an HR or my superior directly with specific instances of problems they have concerns about or feel I am misrepresenting. For my part, I keep records of chats, emails and 1-1s to establish "facts" that drive any decisions I make, especially when it comes to life-affecting decisions like these.
