1. Request or require that an employee or applicant for employment take a polygraph examination.
2. Administer, cause to be administered, threaten to administer, or attempt to administer a polygraph examination to an employee or applicant for employment.
3. Require that an employee or applicant for employment give an express or implied waiver of a practice prohibited by this law.

Employees may voluntarily request to take a test; if the employer agrees, numerous rules apply.

For purposes of this law, employer means a person who employs one or more persons or who accepts applications for employment, including an agent of an employer.
