Introduction:
Frederick Winslow Taylor and Henry Fayol were two of the most influential thinkers in the field of management. Both of them made significant contributions to the development of management theory. However, some of the techniques suggested by Taylor violate the principles given by Fayol.

The Technique that Violates Fayol's Principle:
The technique that violates Fayol's principle is Taylor's technique of scientific management. Scientific management is based on the idea that work can be studied and analyzed scientifically to identify the most efficient way of doing it. Taylor believed that the best way to increase productivity and efficiency was to break down work into small, repetitive tasks that could be performed by workers with minimal training.

Explanation:
The technique of scientific management violates several principles given by Fayol. Some of them are:

1. Unity of Command: According to Fayol, each employee should receive orders from only one superior. However, in scientific management, workers receive orders from both the supervisor and the time and motion study engineer.

2. Unity of Direction: Fayol emphasized that there should be a single plan of action to achieve the organization's objectives. However, in scientific management, the time and motion study engineer and the supervisor may have different plans for achieving the same objective.

3. Authority and Responsibility: Fayol believed that authority and responsibility should go hand in hand. However, in scientific management, the time and motion study engineer may have the authority to determine how the work should be done, but the supervisor is responsible for ensuring that the work is done correctly.

4. Division of Labour: Fayol suggested that work should be divided among individuals based on their skills and abilities. However, scientific management breaks down work into small, repetitive tasks that may not require any specialized skills.

Conclusion:
In conclusion, the technique of scientific management suggested by F.W.Taylor violates several principles given by Henry Fayol. While scientific management may have been effective in increasing productivity and efficiency in the short term, it is not a sustainable approach to management as it fails to consider the human element of the workplace.
