If they haven't ever formally established the rule that you can't wear boots, I think it's pretty crappy of them that they all of a sudden decided to take you off of the schedule without informing you that it's a new rule. Regardless of them being newly concerned about the liabilities or any potential lawsuits, they shouldn't have said "oh I don't know" one day and then just taken you off the schedule as if you broke one of the rules. They never established the rule. Sounds like they're acting dumb. I work part time as a bartender & have one boss that's a neurotic jerk also so I may just be speaking personally because I'm imagining him doing this to me and me getting super annoyed.
