About 36 percent of men and women have cheated with coworkers, according to the Journal of Marital and Family Therapy, and those are just the ones who admit to it. There’s also evidence that the better people are at their jobs, the more likely they are to cheat.

It can start with something as seemingly innocent as jokes about having a “work husband” or “work wife,” marriage and family therapist Talal Alsaleem warns.
