I had a brief stint trying to work at a local Mart starting with K.
I was attending college full time and they insisted on scheduling me 39.5 hours/week, overlapping class times, and when I went to correct them the personnel manager acted like she'd never seen my availability schedule before... THE SAME ONE I GAVE WHEN I APPLIED.
I worked exactly three months there. At two and a half in, the SM called me into her office to speak on my "attitude problem" and tell me that I might not have a job in another two weeks when my "training time" was up.
Another huge joke, they train you for all of four hours and then throw you to the wolves.
I laughed and told her I definitely wouldn't be there in two more weeks, because the place wasn't worth minimum wage with no benefits and zero actual breaks.
Training at many retail jobs is exactly what Michael said, "Four hours and then throw you to the wolves." Share with RHU your worst training experience in comments.
