The federal Americans with Disabilities Act (ADA) also allows employers to require physical exams but imposes slightly different requirements.
Applicants. With respect to job applicants, no exam may be given until after a conditional offer of employment has been made, and then only if the exam is required of all prospective employees for the job. An employer may ask a prospective employee whether he or she can perform job-related functions.
Employees. A physical exam may be required of an employee if the employer must determine whether the employee can still perform the essential functions of his or her job.
Unlike the Louisiana law, which covers employers with 20 or more employees, the ADA covers employers with 15 or more employees. Louisiana employers subject to both the ADA and Louisiana law may require physical exams only after extending a conditional offer of employment.
Additional information on the ADA's requirements is available.
