I became convinced my company was the dumbest possible, mistake after mistake, some really inept managers. And yet, they survive.
I realized other large companies are basically in Dilbertland also.
I spent my last 10 years in a complete sinecure, and they replaced me with TWO people, at the same level. I was content at that point with the pointless job, pretty burned out, NAAFI as a friend called it, No Ambition and F All Interest. I also learned one can skip "mandatory" meetings at will and nobody cares.
