There is one trait that I try to avoid in myself and when I hire people to work for me. This is the demeaning of other people or organizations that they’ve previously worked for.
We show our own character when we describe others. Whether they’re people or companies.
When a man has had problems with all of his previous employees or all six companies he’s worked for in the past, the problem might not be the company or the other people. It’s probably the guy.
If we speak well of those who aren’t around to defend themselves, we show confidence, competence, and responsibility.
Also, people will take your complaint more seriously when you’re not complaining all the time.
