I haven't had many jobs so far as i'm quite young still but this summer, I worked at a recycling center where we would pretty much sort out peoples recycling bins. It stank and was quite dirty, + we would work night shifts (16h00 - 24h00) from monday to friday. At least it was decently paid (1$ over minimum wage) and I had a friend there so it wasn't as boring. In all honesty tho, i'm never going there anymore.
Got good working experience from it and, and now that I know how shitty of a job some people have, I am careful with what I throw in the recycling bin. Now I have a better job (I fry chicken and fries at a local supermarket) which isn't bad at all imo.
