3. The output increases. Usually, in practice, the output increases as a result of the fatigue-recovery periods. Increased outputs encourage both management and worker. They must, however, be inspected and controlled. Some one with the proper training must be in charge, that excessive fatigue may not be accumulated, and the rest periods lose their purpose. With the increase in output must come added compensation in wages. If this is provided, the fatigue eliminating campaign will not be regarded as a new scheme for driving the worker. Better for the good of the management and the men to limit the output to its usual amount during this period, until the workers see that too much fatigue to-day interferes with the standard quantity of output to-morrow, than to attempt to allow increased output without increased pay. The world can better afford to lose the extra product, than the management to appear even for a moment to be trying to overwork the men. 4. The spirit of co-operation grows. The worker realizes instinctively, if the survey has been properly made, and if this preliminary work has been properly done, that the aim of fatigue study is the good of all concerned. There is a psychological element to this. It might be possible to question the motive of installing fatigue eliminating devices. There is no question as to the motive in installing the resting devices and rest periods. The rest periods allow time for development of the social spirit. “To know all is to understand all,” a wise Frenchman has said. “I like every one whom I know,” is the thought of another wise man. “Let’s go at the fatigue survey all together,” is the fifth slogan. The Home Reading Box Movement is, perhaps, the channel where this spirit of co-operation expresses itself most freely. Summary. Preliminary provision for rest for overcoming fatigue consists of establishing rest periods, providing chairs or other devices in which one may rest, and establishing or encouraging betterment work. These result in a more vital and intelligent interest in fatigue, and a spirit of co-operation. This work is embodied in five slogans. These are as follows: “Time to rest when one needs it;” “A seat to rest in;” “A seat for each and every worker whether he needs it or not;” “It is your duty to rest when you need it,” and “Let’s go at the fatigue survey all together.” CHAPTER IV THE HOME READING BOX MOVEMENT What It Is. The Home Reading Box Movement is a system of placing interesting, educational, and valuable reading matter at the disposal of the workers in an industrial organization. It consists of 1. A box in the plant in which the reading matter can be placed and kept until taken out by the workers. 2. Boxes in the homes of members of the organization or of the community interested, where reading matter intended for the plant can be kept until it is collected.
