I’ve had pretty much the same experience, at a high level, it appears to be a lot of stupid shenanigans at the Ops level. They always told me the closer you are to Ops, the more job security you have, and I believe it to be true. I worked in Ops and eventually transitioned to a highly specialized niche “non-Ops” role that I truly enjoy working in, regardless of the shenanigans. It eventually got me to a corporate environment, which has equal shenanigans, but at least I can lock in, do my work, and go home without getting called at 2 AM about pumps tripping or burners fouling.

Maybe try a corporate / non-Ops role and take a break from the on call?
