This or that form of stimulation of labor only then becomes an incentive force when it becomes a motive, that is, when it is accepted by a person, it meets any human need. For example, in order for a monetary reward to become a motive for the conduct and activity of an employee, it is necessary to realize it as a fair remuneration for work. Then the desire of a person to deserve a prize (as a motive of activity) contributes to the improvement of labor efficiency. For employees who do not expect to receive this promotion because of low training or personal lack of discipline, the cash prize does not become a motive, remaining at the stimulus level, because it was not accepted by them as motivation (did not become a motive).
The stimulus may not develop into a motive in the event that it requires impossible or unacceptable actions from a person. As a consequence, he will be rejected, rejected. For example, a proposal to a team of builders of a large amount of money for the construction of a complex facility will not become a motive for them if they do not have the necessary qualifications or do not have the necessary equipment and equipment.
