Cumulative trauma disorders (CTDs) are becoming a major health hazard among phone directory service operators. In order to clarify the causes and to reduce the occurrence of CTDs, a site survey was done. The survey includes observation of the task and the working environment. Also, operators were closely examined and diagnosed to understand the exact causes of CTDs. Different types of CTDs were identified and the most cases were developed in a two or three-years after using new VDT-based workstations. The various design features of workstation aggravated the developemtn of CTDs together with the intense workload. The ergonomic resolutions were suggested based upon these observations.
