Discuss F.W TAYLOR`S motivational theory

In 1911 F.W TAYLOR said money is the main motivator, money makes employees work effectively although there were some people opposing what Mr. Taylor was saying because people can get paid while they are not doing anything at all or working effectively. for you to know how the employee is working effectively there is a need to measure their working progress and there is nobody who would like to be measures in order to get paid.
