I'm a lifeguard at a pool in a gym. It's a small pool, so there's only ever one person on duty at any time. I started about a year ago and quickly became my bosses #2 because I am a fairly hard worker.
I recently got made full time and work 8 hours a day, 5 days a week. We have about 15 employees on staff who work 1-2 4 hour shifts a week. And somehow at least 2-3 times a week I'm asked to cover all or part of the shift for the person after me, or I'm asked to come in on my days off.
I don't want to work a 12 hour shift, nor do I want to work 7 days a week. I did that all summer since most of our staff is college students who were gone all summer. Now that they're back I don't want to keep busting my ass and having no social life because they're all too irresponsible to have a job. I was asked to work a 12 hour shift all 5 days this week and I'm just sick of it. And I also always feel bad saying no whenever my boss begs me to stay extra/cover shifts.
Edit: Forgot to add that I work mostly weekday mornings/ early afternoon and my fiance works afternoons, evenings and weekends. So anytime I work extra I don't get to see him.
Just looking for any advice, comments, etc.
