The supervisor may focus solely on the content level by assigning a specific task that needs to be completed to one of his employees. The employee, on his part, is focused on the emotional level because he does not feel supported. This leads the employee to perceive the supervisor’s communication style as condescending or dismissive.
"Felix, I noticed a frown on your forehead and a change in your expression when I mentioned the salary discussion. It seems like this topic makes you uncomfortable. Is that the case?"
Felix might confirm: “Yes, it does.” You can then explore the reasons behind his discomfort.
Alternatively, he might deny it: “No, everything’s fine.” In this case, you can either continue the discussion or suggest a short break if time permits.
