Long story short. I finished school recently, and have a huge student loan to pay off. I care a lot about money at the moment. I have two jobs: one doing tech support (ts), the other doing brand ambassador work(ba). The tech support is with a reputable company as has room for advancement. It’s 40 hours a week and pays minimum wage (which is very low where I live). The ba work I get to choose the days I work and pays twice as much as the ts. The thing is there’s no room for advancement and its got nothing to do with what I went to school for. My ts job has 5 "paid sick days" which actually can be used for anything you want (not just being sick). I used them up to take on shifts with the ba work, and I used 2 more. Since I called in sick twice more after using my paid sick days, I got flagged as unreliable. I had a talk with my manager today. I told her I was working another job. She said that if it happened again I would get written up, and after 3 write-ups I get fired. She does seem reasonable and said "she is there to help me".
Unfortunately, I have already committed to a ba job on Sunday, and I’m scheduled for my other job as well. I would like to avoid it, but if it comes to making a decision I would take the ba work because
1) It pays better 2) The people I work with treat me better
My question is, how can I explain this to the manager at my other job? I would like to remain on good terms, and now that I’ve got a warning I can cut back on my other work. My goal with the company I’m doing ts for is to stay for 9 months to get access to the internal job postings but I’m also thinking of switching part time to pursue other sources of employment.
TL;DR I’m basically wondering how to say "this job doesn’t pay enough and I am forced to work a second job that conflicts with this one" to management.
Also, is it legal for them to fire someone for being sick more than 8 days in a year? What does it matter to a company if your sick or busy with another responsibility?
