In Australia school age kids (early/mid teens) often do “work experience” in their school holidays or after school. They approach local businesses they might have some kind of interest in learning and spend that time unpaid and helping out. You get exposed to how a business works, prob have to do the boring or messy scut work, but that’s part of it; and when they finish up if they had a good attitude and were productive and worked hard - it can many times turn into a part time job. At the least you could get a written reference from them about your time there, and use that to start building out your CV and help you get a job elsewhere. It’s also great for helping you work out what you might like to do moving forward. At the least if your home dynamic isn’t always great and your folks can be a bit overprotective - it’s a structured way for you to spend some time out of the house that they may find more reasonable and be more comfortable with than your going out and just getting a job. They need to transition into you getting older and more independent too.
Yep “who watches the watchmen?”
