Question: The City of Auburn, a public employer, decides that it wants its employees to participate in a health risk assessment program as a condition of being eligible for the employer's health plan. The program involves the employees filling out a health-related questionnaire, taking a blood pressure test, and giving a blood sample for screening. The results of the tests were only given to the employees, and the employer only received aggregate results. Employees who did not participate in the assessment were not eligible for coverage under the employer's health plan. Does the employer violate the ADA by requiring participation in the health risk assessment as a condition of participating in the health plan? Explain.
