A team member has recently been promoted to be team leader of one of my teams. During a recent staff meeting people were discussing communication within the organisation and how things could be improved. The  Team Leader then went on to say that he would like to know "what you managers do all day". I feel pretty peeved by this comment especially as I worked hard to help a team member get promoted and felt unsupported by her in the meeting. I operate an open calender and people can see my schedule and I meet most people weekly. Do I address this with my team lead or let it go?
