This story reminds me of my last 10 years at Verizon.

Constantly swimming against the tide in an unhealthy toxic work place at Verizon without getting caught in a RIFtide was a mental grind that became worse as time marched on. Same here as in this story: "I was doing what I had always done: doubling down, working harder, stressing more, and trying to control a situation that was out of my hands." Eventually it became a game of survival while preparing for that day. Fortunately that day came in the form of a buyout in 2019, otherwise it would have broke me mentally too.
