In a study of telephone operators in North Carolina, Suzanne Haynes of the National Center for Health Statistics in Hyattsville, Maryland, compared 278 women who worked all day at video display terminals (VDTs) with 218 clerical workers in the same companies who did not use VDTs. Twice as many VDT users reported chest pains as clerical workers in the same companies-20 percent compared to 10 percent. Perhaps, Haynes commented, "VDTs can be the ultimate nonsupportive boss."
