Why? Because employees are more sensitive to mood than leaders often realise. And these moods are contagious. Research carried out by Caroline Bartel at New York University and Richard Saavedra at the University of Michigan found that in 70 different teams, people working together in meetings ended up sharing moods – whether good or bad – within two hours. And bad moods spread faster than good ones.

In their 2001 Harvard Business Review article “Primal leadership”, Daniel Goleman, Richard Boyatzis and Annie McKie argued that one of the key duties of leadership – they say it is the most important one of all – is to manage your emotions with care.
