Happiness and work. The two words don’t seem to sit well together. Work is about the stuff we have to do. Work is about effort. Work is tough. Happiness, in contrast, is about fun things. Happiness is light. Happiness is even a bit soft and fluffy. So perhaps it is not surprising that people’s happiness at work is not taken that seriously by organisations. But I want to explain why this is a serious business mistake and a serious misreading of what happiness is really about.
