While corporate protection of employees has long been a priority, increased awareness of the sensitivity of the fetus to low level chemical exposure required that women of child-bearing age be given additional protection from over-exposure. The U.S. Supreme Court decision (International Union, United Automobile, Aerospace & Agricultural Implement Workers of America, UAW, et al. v. Johnson Controls, Inc., 1991) extended this protection to men. This resulted in a wide variety of programs aimed at offering increased protection to any employee who is actively pregnant, has a pregnant spouse, or is trying to get pregnant. The Johnson Controls case serves as a guide against which fetal protection programs can be evaluated. Over the period of 1985 – 1995, a major petrochemical company refined its existing fetal protection program to be consistent with the legal requirements of Johnson Controls. Valuable lessons learned are relevant today.
