Is my mum crossing the line?

I need to vent about my current situation because it feels a bit overwhelming. So, here’s the deal: I’m a 17-year-old with two jobs—one at a cafe, which I really can’t stand, and the other in fire rescue, which I actually enjoy. The cafe job isn't terrible, but it's just not my vibe, and honestly, I dread going in. My boss has neglected me for months, not giving me a single shift, and then suddenly she starts calling at the most inconvenient times, expecting me to jump in for shifts like I'm some kind of emergency responder.

Just the other day, she called me at 7 AM to see if I could work a shift that started at 9 AM. Of course, I didn’t see her message until 8:30 and, after looking at it, I just rolled back over and went to sleep. This has happened several times, and when my mum found out I hadn’t taken these shifts, she decided it would be a good idea to give my boss her number. Now my mum wants to get involved when I’m contacted about work, which feels like such a violation of my independence.

I mean, seriously, how often do you hear about parents monitoring their 17-year-old's job responsibilities? I’ve had to learn to be self-sufficient because my parents have focused so much on my autistic brother throughout my life. I’ve become pretty independent because of that, and I really value it.

So, I’m left wondering: Am I being unreasonable for feeling frustrated with my mum, or do I have a right to be annoyed?
