There's no secret that in order to have high-performing teams, all members need to be happy. It is a fact not only supported by us but one that has been scientifically proven over 10 years ago.
Additionally, research shows that people are more likely to be happy making kind gestures to others than when pursuing happiness as a personal endeavor. The explanation behind this theory is simple. When we focus on others and not ourselves, we tend to develop more positive emotions. And that leads to a flourishing state of mind.
A while back, a study concluded that people's happiness increases when they work side by side with their colleagues. This creates the opportunity to help each other out and spread their well-being from one person to the next.
This is why it is very important that you, the leader, coach your team members to be kind to one another. Teach them to do so not because they expect something in return but because it is the right thing to do. Guide them on how to help their teammates when they need assistance but also how to say thank you when they are the ones who receive support.
