<human>: So, I started at my current job about 18 months ago, when I was 18. Right from the get go, my boss was slack with pay and has never given me a pay slip. Being 18, I wasn't too worried, but about 16 months down the track I've been very unimpressed with the position I've been put in. After searching for a job for quite some time, I was offered one today. Issue is, they only do training once a month (big company) and the training is this Saturday (my next shift at my current job). I'm a casual, and at the moment I'm only working about 1 day a week. I handed my boss a letter three weeks ago stating he owes me over $1000 in unpaid wages, which has still not been resolved despite be stating I needed this to be resolved by the next week. It's Thursday night now (Australia) and I'm at university until 4pm tomorrow. Is it bad form to go in and quit tomorrow afternoon before my next shift - and risk never getting paid, or should I wait the month and risk working for nothing? Or an alternative?

Can you give me a shortened version of the text?
<bot>: my boss continually doesn't pay me, and I can go to my new job Saturday, but I have a shift with my current job that day.
