A reader writes to say that a coworker betrayed her. “He pretended to be my friend. But then he went behind my back, revealing a secret to our boss that got me in a lot of trouble.” She also says he set her up by encouraging her to take an action that he later used against her — although she didn’t find out for many weeks.
Now trust is an important part of any workplace. And when someone betrays you — especially a supposed friend — that can knock your trust level down to zero pretty quickly.
