The fourth provision for rest is really a part of betterment work. It must be described at some length. This is the Home Reading Box Movement, which furnishes a definite means for making rest periods, both at work and at home, attractive and profitable. Before turning to a description of this, we may estimate the effect upon the worker of the preliminary work so far done. Results. The results of the preliminary work we have done are as follows: 1. The interest in fatigue becomes more vital. We have aroused more interest in fatigue elimination, and have made it general. With the establishment of properly distributed rest periods, chairs, seats, etc., the recovery process becomes interesting. As he knows how resting improves his working conditions, the worker becomes more warmly interested in the fatigue itself. It is a very different thing to talk about the evils of fatigue, or even to see the advantages of proper rest exhibited in object lessons, than it is to get proper rest in a specially designed chair for the first time in one’s working life. Fatigue, which was _an_ enemy, becomes now not only _my_ enemy, but _our_ enemy--mine, because I recognize it has affected me; _ours_, because we are fighting it together for our best interests, severally and collectively. 2. The interest in fatigue becomes more intelligent. Many workers, especially women, feel that it is to be expected that they will get exceedingly tired by night; that one cannot expect to do so much late in the day as early in the day; that stopping to rest is cutting down one’s output, thus cheating one’s self, if one is a piece rate worker, or cheating the management, if one is a day rate worker. The worker now comes to realize that he hurts the management _and_ himself, when he gets too tired. “It is your duty to rest when you need it;” that is the fourth slogan. It must be remembered also that the rest periods provide time for clearer and more intelligent thinking. It is impossible to come to any valid conclusion when one is working at top speed part of the day, and in a state of exhaustion the rest of the time. We have now an opportunity to think, and brains rested enough with which to think.
