Mary Parker Follett's primary criticism of Taylor's system of scientific management was that it did not allow workers to exercise initiative and contribute to the organization.
Taylor's approach, known as scientific management or Taylorism, focused on maximizing productivity through strict regulation and control of workers, without much concern for their well-being.
