by my manager. After getting my morale seriously pummelled for several months, I sent the CTO of our organization git blame logs that showing I was being beaten up for trivial things that my manager's most senior reports had in fact taught me to do and that they had coded and shipped out to clients on other projects my manager was overseeIng.
Needless to say...I was shown the door a few months later. This would have happened anyways, but at least by confronting the gaslighter with hard evidence I can look at myself in the mirror and I'm not the emotional wreck I'd be if I sat back and did nothing. I don't regret it in the least.
And just maybe I made small dent in that jerk's ability to gaslight others in the future.
