This study reports the results of an investigation of the relation between one measure of the performance of firms, work injuries, and the number of first level supervisors for 140 chemical, paper, and wood product manufacturing firms. Additional numbers of supervisors were found to be associated with lower work injuries in most cases, and the cost of such additional supervision was found to be partially justified in terms of the reduced costs of work injuries, although there was considerable variation across industry.
