The Psychology of Management by Lillian Moller Gilbreth

2. The idea of brotherhood is fostered particularly through the

responsibility for others, through the feeling that grows up that each man is dependent upon all others, and that it is necessary for every man to train up another man to take his place before he can be advanced. Thus it comes about that the old caste life, which so often grew up under Traditional Management, becomes abolished, and there ensues a feeling that it is possible for any man to grow up into any other man's place. The tug-of-war attitude of the management and men is transformed into the attitude of a band of soldiers scaling a wall. Not only is the worker pulled up, but he is also forced up from the bottom.[4]
