Labor productivity


The purpose of this study was to determine if membership in a labor union has an effect on the productivity of workers in manufacturing industries. Two independent studies were used to collect information on worker productivity. The first was a case study of a special tool manufacturing company that operates two facilities. One facility employs workers that belong to a labor union; the other does not. The study showed there was little difference in the productivity of either group of workers. The second study consisted of a productivity survey mailed to randomly selected manufacturing firms. Respondents to the survey furnished productivity information on both union and nonunion workers. The results of this survey showed no significant difference in the productivity of union and nonunion workers. Based on the results of the two studies, the null hypothesis was accepted. This hypothesis states that in manufacturing-type industries, where productivity is measured as the output per hour of the workers, there is no significant difference in the productivity of employees belonging to a labor union and the productivity of employees who do not belong to a labor union.
