1994). This was designed to first, to determine what types of occupation causes different kinds of fatigue. Second, to assess how unnecessary fatigue can be eliminated. Third, to reduce the amount of fatigue in the workplace as low as possible. Fourth, to determine different methods to combat fatigue. Fifth, to put the information gathered by the study in a form that the average worker can understand. The two types of fatigue are necessary and unnecessary. Unnecessary fatigue is caused by work that uses more energy to accomplish a task than is needed or performing a job that should not be performed to reach a goal (Myers 1953). A good example of wasted energy is the work of the bricklayer. The method for centuries was for the bricklayer to raise his body, the mortar, and the bricks from the ground to the top of the building (Gilbreth 1916). This type of work used a large amount of unnecessary energy. Necessary fatigue is caused by the accomplishment of any task. For example, there might be an improvement to a work method, which resulted in an increase of productivity by fifty percent. Even though more work was accomplished in the same amount of time it did not or can be expected to eliminate all fatigue. One of the most effective ways to reduce fatigue is to improve the work environment of an employee. The employer needs to ensure a worker has enough time to rest and spend time with the family at the end of the day. One of the ways to ensure an employee is not exhausted is to provide a lunch period and at least one day a week off from work. Another method is to ensure the proper equipment is used to perform a task. The Gilbreths did a study, in which, they provided a reclining chair to all workers in a company. After one week of use the company increase productivity with less worker fatigue (Spriegel 1953). Proper lighting in the workplace is another way to reduce fatigue. If a workplace has too much or not enough lighting the workers...
