Effects of Video Display Terminals on Telephone Operators
研究对比了使用视频显示终端和纸质记录的查号员，发现两者在工作不适、工作满意度和工作安全感方面差异很小，表明用VDT替代纸质文件不会对员工舒适度和士气产生负面影响。
A self-administered questionnaire was completed by 145 Directory Assistance operators who used video display terminals (VDTs) to retrieve listings and by 105 control subjects who performed identical work except that they retrieved listings from printed paper records. The two groups exhibited few differences in their experience of work-related physical discomfort, in job satisfaction, or in their concerns about job security. Both groups were found to use eyeglasses and contact lenses to the same extent. VDT operators generally did not obtain special corrective lenses for work. The results show that replacing paper documents with VDTs need not adversely affect the comfort and morale of office workers.
