I can tell you that the store I worked at was poorly managed. The Old Veteran employees would make themselves scarce and leave the rest of us to handle angry crowds of customers who were angry because they couldn't find anyone to help them. I had to stock seven aisles and help the customers too and just couldn't keep up. It was hell for a twelve hour shift.
Don't get me wrong. Retail sucks, and I really wish he was doing something different. Something that doesn't make him lift weights and where the hours are a little more condusive to family life.
Sounds like the store you were at was badly run. Hubby is very seldom able to get OT, and breaks are MANDITORY.
Usually here it's the part-timers and students who flake.
