Participatory Ergonomics as a Means of Preventing Wmsds

Abstract

Participatory ergonomics is a flexible means for the achievement of many diverse goals in turbulent technological environments. It is a macroergonomic approach to the implementation of technology in organizational systems which requires that end-users be highly involved in developing and implementing the technology. The notion of participation offers the promise of tremendous potential gains for the organization, the worker, and even the economic well-being of the greater society. Such pervasive and important technological innovations as the use of computers and their concomitant video display terminals can, in spite of their usefulness, lead to many occupational health and safety problems. Cumulative trauma disorders appear to be an associated dysfunction in modern industry, and effective health and safety solutions to many of these problems are highly important, both to the organization and especially to the people in it. It is proposed that the use of participation and worker involvement in the solution of such problems is a powerful and promising tool. There is no one best way to employ worker participation. It is contingent upon the nature of the problem itself, the work system, the job design presently in place, the environment in which the work is done, the training of the worker, and a myriad of other variables. From the available empirical evidence, a participation typology is postulated. The successful implementation of participatory ergonomics and other participatory arrangements requires the empowerment and enablement of people to make decisions concerning their work and to implement and evaluate them. Several participatory approaches to worker involvement are presented which address work system and job design factors, design of the work environment, and training of VDT operators. These approaches are discussed in the context of a systems approach to the prevention of WMSDs. The reduction and/or prevention of cumulative trauma disorders such as work-related musculoskeletal disorders is a matter of great concern in modern organizational life, both from the point of view of productivity concerns and also from that of the humanization of work. The solution of occupational health and safety problems will not only lead to increased organizational effectiveness, but should help provide for a far better realization of human potential.
