So through a variety of work-related drama that really doesn't matter, my direct manager's position has opened up. I've essentially been doing the job but without the title for a fair bit of time so I decided I might as well try to get the position officially. I later found out that the position I applied for isn't actually a union position and it's kinda made me start rethinking things, as far as I'm aware it shouldn't actually affect the benefits or hours, just a non-union unit manager position.
Take the position and be an advocate for the workers that report to you.
A manager that sticks up for their team is important, and sometimes tells upper management the things they need to hear (like the word NO) that turn out to be better for the company long term.
