It's a glass of wine - for ONE!
This is the leader who takes ownership of success and does not congratulate the team...or even acknowledge the participation of the team.
What to do? Open your own bottle of wine and celebrate - you know you did it and that the insecure and arrogant leader/boss you have is simply basking in his own glory. Slip the success into conversations in the future giving credit to everyone involved - this will help the leader see that others are on the team and that without a team, he would not be a leader.
