Abstract
An expanded activity analysis was developed to characterize the task functions of clerical workers in telecommunications. The analysis focused on task repetitiveness and task constraint as risk factors since both attributes have been identified as contributing to the development of cumulative trauma disorders. The following five jobs were considered: directory assistance operators, centralized mail remittance employees, service representatives, employees of a recent change memory administration center, and employees of a loop provisioning center. Workers from each of the job categories at three job sites were videotaped during seven to 20 job cycles. Each of 66 samples of work was reviewed using a video recorder editor system. Several risk groups were established from the data collected. The directory assistance operators, service representatives, and centralized mail remittance workers had task constraint ratios above 0.80. Service representatives and centralized mail remittance workers had longer cycle times than directory assistance operators.
