What is the meaning of 'Espirit de corps' ?

Union is strength

It is one of the fourteen principles of management developed by Henry Fayol. Esprit De Corps means union is strength. Management should promote a team spirit of unity and harmony among employees, according to Fayol. Management should promote teamwork especially in large organisations because otherwise objectives would be difficult to realise. It will also result in a loss of coordination. A manager should replace ‘I’ with ‘We’ in all his conversations with workers to foster team spirit. This will give rise to a spirit of mutual trust and belongingness among team members. It will also minimise the need for using penalties.
