Abstract
Although few companies are currently applying genetic tests or using genetic data, further developments in genetics will likely increase the role of genetics in the workplace. This article discusses the complex ethical issues raised by the variety of genetic tests that could become available and proposes guidelines for dealing with genetics in the workplace. It discusses how the results of genetic testing could be used for employment purposes, and argues that the existence of unequal bargaining power in the workplace limits the validity of consent as a basis for policymaking. Instead, two specific justifications for genetic testing in the workplace are proposed: the protection of health and the avoidance of harm to others. The author suggests that genetic testing should be permitted only in exceptional circumstances and that every genetic test should be evaluated on its scientific validity and submitted to rigorous review. Existing antidiscrimination law proves to be a useful model for examining the rationality and proportionality of genetic testing in the workplace.
