THREE RATE WITH INCREASED RATE SYSTEM.--The Three Rate System of Compensation is the invention of Mr. Frank B. Gilbreth and consists of day work, i.e., a day rate, or a flat minimum rate, which all who are willing to work receive until they can try themselves out; of a middle rate, which is given to the man when he accomplishes the work with exactness of compliance to prescribed motions, according to the requirements of his instruction card; and of a high rate, which is paid to the man when he not only accomplishes the task in accordance with the instruction card, but also within the set time and of the prescribed quality of finished work. ADVANTAGE OF THIS SYSTEM.--The advantage of this is, first of all, that the man does not have to look forward so far for some of his reward, as it comes to him just as soon as he has shown himself able to do the prescribed methods required accurately. The first extra reward is naturally a stimulus toward winning the second extra reward. The middle rate is a stimulus to endeavor to perform that method which will enable him easiest to achieve the accomplishment of the task that pays the highest wage. The day rate assures the man of a living wage. The middle rate pays him a bonus for trying to learn. The high rate gives him a piece rate when he is skilled. Lastly, as the man can increase his output, with continued experience, above that of the task, he receives a differential rate piece on the excess quantity, this simply making an increasing stimulus to exceed his previous best record. ALL TASK SYSTEMS INVESTIGATE LOSS OF BONUS.--Under all these bonus forms of wages, if the bonus is not gained the fact is at once investigated, in order that the blame may rest where it belongs. The blame may rest upon the workers, or it may be due to the material, which may be defective, or different from standard; it may be upon the supervision, or some fault of the management in not supplying the material in the proper quality, or sequence, or a bad condition of tools or machinery; or upon the instruction card. The fact that the missing of the bonus is investigated is an added assurance to the workman that he is getting the "square deal," and enlists his sympathy with these forms of bonus system, and his desire to work under them. The fact that the management will investigate also allows him to concentrate upon output, with no worry as to the necessity of his investigating places where he has fallen short.
