My boss took over some work I'd begun. Concerned that she had doubts about my work, i asked her for feedback. I assured her that I did my utmost for customer service, and asked if I was deficient. She then said this was me being co-dependent.
How do I assert myself with a boss who called me co-dependent?
This interaction with your boss seems strange. It is tricky to know how to handle workplace conflicts, but there are typically resources in place to help employees and mangers communicate successful and feel confident that they are being treated fairly at work. Is there an HR department that you can use as a mediator?
