Having a stressed-out boss
When your boss is obviously agitated, speak and react in calm ways. Have your work ready in advance of the deadline. Remind him of upcoming tasks or events. Offer to take on any of their tasks that you know you can handle that he can have some uninterrupted time. Suggest the two of you go for lunch, a coffee, or a walk. Listen him actively, be present in the moment. You might hear precious information from him to be used later.
