And if I'm her manager's manager, two points: 1. I have failed to train the manager properly, and need to consider whether that's because I'm a bad manager or the environment is such that it's time to leave; and 2. If I have spent some effort with my team and this manager to prevent such idiocy, the manager who made the decision needs to be either demoted or fired. This is a more common scenario in customer service than it should be. The fact that seniority was the only criteria is an indicator that it's not a good environment. The fact that this manager thinks she needs to lecture the woman who quit on "professionalism" (especially for the reasons stated) is an indication that it's a terrible environment. But I'm inclined to believe this is someone trolling "ask a manager." In what customer service job does someone with six years' tenure have lowest seniority?
