The two principles that are being regarded in the given paragraph are as follows:
(i) 'Harmony, Not Discord' by Taylor: Taylor emphasized that the managers and the workers should maintain a harmonious working environment. He introduced this principle to maintain a peaceful connection among people. Often it is found that if the workers are deprived of their wishes or demands they generally go on strike. This affects the productivity and the working environment as a result organisation cannot achieve its goal. To dismiss such situation Taylor insists on mental revolution. It implies a change in the thinking of both the workers and managers. For example, if a worker is having problem with the working hours, he should talk to the manager about it, instead of letting it effect the production (by going on a strike). Similarly, the managers should listen to the worker's suggestions and demands rather than ignoring them along with sharing gains of the organisation.
(ii) 'Remuneration of Employees' by Fayol: This can be inferred from the line that the employee's compensation should depend on the earning capacity of the company and should give them a reasonable standard of living. According to this principle, the compensation paid to the employees should be fair i.e., the employees must be paid appropriately as per their work responsibility.
They must be able to lead a reasonable and a decent standard of living. When the employees are paid adequately, they are satisfied and are encouraged to give their best to work. On the other hand, underpaid employees would remain unsatisfied and would tend to leave the firm or not work properly. As a result, the firm would face high employee turnover. Thus, in order to maintain stability and harmony in the organisation, the remuneration paid to the employees should be fair. However, it must be remembered that the compensation paid should be within the paying capacity of the organisation.
