A woman where I work is coming close to retirement (about 2 years to go). She's beginning to take a bit of a back seat at work. She still does her job and does it to a very good standard, but isn't bothered about putting in extra hours, volunteering for committees and so on.
A couple of people have started to talk disapprovingly about 'these people who just want to coast along until they retire'.
AIBU to see nothing wrong with this? She's doing the job she's paid to do but will not be seeking any further promotions, has no need to make her mark or impress management, has no real vested interest in the future direction of the organisation or anything like that.
Surely it makes more sense to pull back if that's what you want, devote more time to outside interests, and leave the other stuff to younger people who still have careers ahead of them, while you prepare for.a new chapter in your life
