Fredrick Winslow Taylor gave the concepts of 'mental revolution' and 'Harmony, Not Discord".

Taylor emphasized that there should be complete harmony between the management and workers. Both should realise that each one is important. To achieve this state, Taylor called for complete mental revolution on the part of both management and workers. It means that management and workers should transform their thinking. In such a situation even trade unions will not think of going on strike etc. Management should share the gains of the company, if any, with the workers. At the same time workers should work hard and be willing to embrace change for the good of the company. Both should be part of the family.
