I worked as a cashier for a large Canadian company....While I was working, I would always hit "void" and "total" on certain products....i had three complaints filed by customers I was unaware about (except I figured out this one couple filed a complaint because I forgot to use their coupon for fifty cents off of something at the exact time my manager gave me a nasty talk). A little over two weeks my human resources manager fired me (after her two week return from vacation). All in all, I don't think my manager had a problem with me. But my supervisor did. No one ever told me that voiding all products to start over would be a big mistake, because while training, that's what one of my supervisors did...No one even told me that people were complaining about me. I felt that I got the basics down, and my coworkers said I was doing fine. And I just think my supervisor didn't like me for personal reasons. Anyway, point is, i got sacked. How do I get over it? I feel very disposable.
