My co worker-worker was explaining her work (we were working together, I being in a supervisor role) and suddenly made a personal comment saying "I“I think we are going wrong with this hit 'n trial"‘n trial.” IMO, this shows low confidence in my suggestions. I am confident that I was methodical in the approach I suggested to her.
Being a senior co-worker to her, what should my actions be? Since the incident I have hardly spoken about it. Meanwhile I am getting mails and direct questions on what to do next, but why would I continue with her on the task when she has shown so little confidence in me?
