I’ve worked for the same company for about twenty years. I’m still rank and file because I’ve repeatedly turned down supervisory roles. Like in your situation, the pay for the more stressful job isn’t much better and comes with a lot more responsibility.

Instead, I negotiated to get myself off the rota system and onto fixed hours. I am the only member of staff outside of upper management who’s on fixed hours. Literally everyone else works shifts. Middle management don’t like that, but I consistently perform well on whatever plausible metrics they dream up, I’m generally well-liked, also they can’t get rid of me because I know where the bodies are buried*.

In summary: I believe you’ve made the right choice, because I made a similar one. But it’s not my choice. The choice is yours alone.

*this is a metaphor for institutional knowledge, as far as I know there are no bodies buried in the old trolley shed behind the Inpost locker
