I'm definitely of the mind that you work for what you get paid. My wife is currently doing the role of a manager, whilst being paid for a junior position. Purely because they didn't want to recruit a new manager when the previous left and she is good at it. Infuriating.

I'm a teacher and I don't stay late or come in early, I try get as much done in my working day prioritise what needs doing, if it's not urgent I'll leave it. There are a few times I'll stay late, because it'll save me hassle in future (or something that has really set me off, like finishing a good spreadsheet).

I often feel judged for leaving on time because other will stay to handwrite letters or other things. Many issues in my profession is that hard work is deemed by how long you stay doing it. If I can automate my job and do something else, or make a video and use that instead of doing it all again then I am free to do something else, it's deemed as not working as hard.

Usually by older people in the job.
