Excerpt from Second Interim Report on an Investigation of Industrial Fatigue by Physiological Methods Further, a lengthened period, caused by the abolition of rest-intervals, a lengthened day, caused by the introduction of overtime, and a lengthened week, caused by an interference with the week - end rest, will lead to a still more rapid production of fatigue and a still less perfect recovery. Even the distribution of the overtime days will affect the result. Since the condition of the worker and his efficiency depend upon these factors, the question of the proper length of period, day, and week. And of the proper distribution of overtime, is one which merits the closest attention. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
