Q: I have one employee, an average performer, who complains about the behavior of co-workers on a regular basis. One time it will be their performance — she feels she works harder than the others and wants it fixed (others see the work being distributed fairly evenly, and the complainer doesn’t ask those available to help when she needs it — just complains later).

The next complaint is about co-workers’ attendance. Her most recent is about people calling in sick or staying home to care for a sick child: She feels that nothing ever happens to those who do this frequently. Now she is saying that if something isn’t done, she will need to leave because there is just too much work and it’s too stressful to stay, and that she doesn’t need to work.
