I did grocery retail for about 4 years. We had some less-than-great customers but honestly the worst part was dealing with corporate. Upper management and corporate decisions is what truly made daily work much more difficult. The store manager that was there when I was hired was really good and good to her staff, but corporate didn’t like that she ran some expenses for customer and employee benefit so they “relocated” her. The replacement manager was one of those “fixer” types and he so godawful that I walked off the job. Left my badge on my department desk in the office and went home. Because they had been cutting back hours and hires, my entire department folded after I left. My supervisor got reassigned and some of the other part-timers left.
