Here is an interesting article I ready by Robert Quinn.
I thought this part was particularly of use in dealing with workplace bullies:
“Positive emotions transform individuals into more resilient, socially integrated, and capable versions of themselves.” As we apply principles that cause of us to feel more positive, authentic and courageous, we then engage in more positive, authentic and courageous acts. We thus become emotionally contagious in that we inspire more positive, authentic and courageous feelings and action in others. They then do things that inspire us and our relationships become a virtuous cycle. As we live in such a virtuous cycle, we flourish in the paradox of the positive.
