I went on a job and they gave me uniform and trained me for few minutes then I worked as normal for the rest of the shift. However, I decided this is not for me so I quited. Now they don't pay me for that day, is this legal? They argue that they spend money on uniform (I returned it) and that I was training on that day (which is not true, because I just did the job for the rest of the shift). I was never told that first day would be training and it would be unpaid. Any advice?
