This happened to me a few years ago.
I was interviewing for for a few jobs in a new area I was moving to. I got an interview for an Assistant Manager position at a woman's clothing store in one of the largest malls in the country (Canada). During my interview, pay was brought up by my interviewer. I made it clear I would only accept the position if I was making above minimum wage ($12.50 cad at the time). The interviewer assured me that as Assistant Manager I would definitely be paid above minimum wage.
Jump to a few days later when they call and offer me the job. I stated on the phone that I would be happy to take the position as long as the pay was good.
I show up for my first day of orientation. I am handed my employment contract to sign and OF COURSE they tried to slip into the Co tract that my wage would be $12.50/hr. Minimum wage. Needless to say, I only worked the one day and got the hell out of there.
JUST PAY PEOPLE WHAT THEIR JOB IS WORTH.
