If you manage people long enough, it’s likely you’ll come across someone who constantly complains. This is a person I know well. In addition to having a few of them work for me over years, I use to be one.
The funny thing about the constant complainer is that very often, he or she is one of your best employees. In fact, part of the reason they complain so much is that they have high standards for themselves, their peers and the company. So what can you do if you have this type of employee?
