Stress factors are reviewed in relationship to the area of secretarial and clerical work. Fatigue is discussed as a response to stress and the general fatigue which affects some workers as the culmination of several smaller incidents of fatigue. The presence of several stress factors was sought in the job situation including: visual problems, postural and anthropometric concerns, environmental trouble spots, difficulties encountered in task organization, and higher order stress factors. Cathode ray tube (CRT) operators and keyboard operators in general complain frequently of visual and muscular disorders resulting from factors peculiar to their work tools. Sometimes design defects or poor posture habits are at fault in creating the stressful situation. Solutions to these problems are presented as being either low technology or high technology. The low technology solutions include following standard ergonomic practices, avoiding the use of overhead lighting fixtures, using screen hoods and antiglare coverings, correcting individual visual problems for the workers, and establishing frequent work periods. High technology answers include improving CRT tubes to enhance the ratio of symbol luminance to screen luminance, reducing flicker, establishing standards and threshold limit values for exposure to CRT displays, and using psychometric techniques to estimate the quantity of visual discomfort being experienced by the worker. The work is concluded with an annotated bibliography.
