Presently, there are few legal restrictions on the use of medical screening of workers. The Occupational Safety and Health Act (OSH Act) requires that certain medical tests be performed when workers will be exposed to specific toxic substances. The OSH Act does not, however, prohibit the use of any medical screening measure nor does it indicate what actions an employer may or may not take as a result of such information. (A notable exception is the medical removal provision of the Lead Standard.) This paper discusses that protection afforded under Title VII of the Civil Rights Act of 1964, the Age Discrimination in Employment Act, and the Rehabilitation Act of 1973. This paper will demonstrate that the law has, in general, failed to take into account the discriminatory aspects of medical screening.
