Most employers may not use lie detector tests in connection with pre-employment screening or during the course of employment. Exceptions include government and national defense agencies; certain prospective employees of security service firms and pharmaceutical manufacturers, distributors and dispensers; and certain employees of private firms who are reasonably suspected of involvement in workplace incident(s) (theft, embezzlement, etc.) that resulted in economic loss to the employer’s business.
