I'm not sure if this even matters, but my boyfriend lives in the UK. About a month ago he started a job at his local Subway. Instead of having an interview he had a one hour trial shift(it was unpaid). Now he has to do online training outside of work while he's at home. He told me half the time his Subway shop isn't that busy, I feel like his manager is looking for an excuse not to pay him.
Even while I was(and currently)working minimum wage, I was paid for my online training and I was able to get it done on my first shift. I think he deserves to be paid for his work and I think it's infuriating that he's not. I know doing something like this is illegal in the US, I believe it's the same in the UK but I'm not 100% sure.
