I work in a high stress medical setting and have been for 8 years now. I've always been talk to go above and beyond for work. Over the last 4 years I've been increasingly burnt out and my paychecks do not seem to match my effort.
However this past week, after a particularly nasty mental breakdown a few weeks ago, I've been doing the bare job requirements and it's been lovely. I now feel like I have more energy for my life outside of work, and more energy to further myself personally.
Remember it's only a job, do what you have to and clock out.
