“Listen, I should have spoken up in the meeting. It was my idea, and I shared it with George. I was shocked when he introduced it at the meeting as his own. I have been gritting my teeth about this for three wasted days. Usually I just clam up or leave. You know me pretty well, and I think you value me as a team-member. Can we talk about what I can do differently in the future?”
P.S. Sharon has already done something differently!
