I'm kind of in this boat . . . hit 20 years at the same company this year (sort of--we've done some acquiring and been acquired) and it's kind of the "golden handcuffs" situation. I was a manager (sales operations & quasi-IT-related) up until a couple years ago when things got nutty with being acquired and a gigantic chitstorm of a project that I was neck-deep in all at the same time that my dad was cratering from Alzheimer's and mom needed a lot of help. I resigned once teling my boss it just wasn't worth the brain damage & stress anymore and he talked me out of it. A few months later it wasn't any better and I told him I wanted to move to individual contributor or I was leaving. So that's where I've been.
It's been "better" like that but it's getting a bit stupid again . . . company is like a head with its chicken cut off most of the time. But with the pay being what it is and great benefits--and the pandemic--its just not an advisable time to jump unless something comes out of the blue. Probably just try to bank as much as possible for as long as I can stand it and hopefully downshift into semi-retirement in the next 5 years. Maybe find something part time just for basic spending to minimize dipping into other funds.
I dunno. Weird place to be. My wife says I just need to transition to "quit and stay" mode . . . don't kill yourself and do just enough to not get RIF'd. I'm trying to care a lot less, but I'm just not wired that way.
