The manager said, “I think you should just let it go,” and Elaine said she’d try, but you could tell that Elaine was not impressed with that response. Elaine is probably going to be much less likely to share any concerns with that manager because she know she will just feel dismissed.
When the employee expressed concerns over difficult colleagues, the manager completely invalidated them. She just said, “Well, it’s not really what you think. Don’t worry about it. I’m sure they didn’t mean it.” Therefore, in that moment, you saw trust get completely undermined in that relationship.
