(410 ILCS 705/) Cannabis Regulation and Tax Act.
Section 10-50. Employment; Employer Liability.
a) Nothing in this Act shall prohibit an employer from adopting reasonable zero tolerance or drug free workplace policies, or employment policies concerning drug testing, smoking, consumption, storage, or use of cannabis in the workplace or while on call provided that the policy is applied in a nondiscriminatory manner.
b) Nothing in this Act shall require an employer to permit an employee to be under the influence of or use cannabis in the employer’s workplace or while performing the employee’s job duties or while on call.
c) Nothing in this Act shall limit or prevent an employer from disciplining an employee or terminating employment of an employee for violating an employer’s employment policies or workplace drug policy.
d) An employer may consider an employee to be impaired or under the influence of cannabis if the employer has a good faith belief that an employee manifests specific, articulable symptoms while working that decrease or lessen the employee’s performance of the duties or tasks of the employee’s job position, including symptoms of the employee’s speech, physical dexterity, agility, coordination, demeanor, irrational or unusual behavior, or negligence or carelessness in operating equipment or machinery; disregard for the safety of the employee or others, or involvement in any accident that results in serious damage to equipment or property; disruption of a production or manufacturing process; or carelessness that results in any injury to the employee or others. If an employer elects to discipline an employee on the basis that the employee is under the influence or impaired by cannabis, the employer must afford the employee a reasonable opportunity to contest the basis of the determination.
e) Nothing in this Act shall be construed to create or imply a cause of action for any person against an employer for:
1) actions, including but not limited to, subjecting an employee or applicant to reasonable drug and alcohol testing under the employer’s workplace drug policy, including an employee’s refusal to be tested or to cooperate in testing procedures or disciplining or termination of employment, based on the employer’s good faith belief that an employee used or possessed cannabis in the employer’s workplace or while performing the employee’s job duties or while on call in violation of the employer’s employment policies;
2) actions, including discipline or termination of employment, based on the employer’s good faith belief that an employee was impaired as a result of the use of cannabis, or under the influence of cannabis, while at the employer’s workplace or while performing the employee’s job duties or while on call in violation of the employer’s workplace drug policy; or
3) injury, loss, or liability to a third party if the employer neither knew nor had reason to know that the employee was impaired.
f) Nothing in this Act shall be construed to enhance or diminish protections afforded by any other law, including but not limited to the Compassionate Use of Medical Cannabis Pilot Program Act or the Opioid Alternative Pilot Program.
g) Nothing in this Act shall be construed to interfere with any federal, State, or local restrictions on employment including, but not limited to, the United States Department of Transportation regulation 49 CFR 40.151(e) or impact an employer’s ability to comply with federal or State law or cause it to lose a federal or State contract or funding.
h) As used in this Section, “workplace” means the employer’s premises, including any building, real property, and parking area under the control of the employer or area used by an employee while in performance of the employee’s job duties, and vehicles, whether leased, rented, or owned. “Workplace” may be further defined by the employer’s written employment policy, provided that the policy is consistent with this Section.
i) For purposes of this Section, an employee is deemed “on call” when such employee is scheduled with at least 24 hours’ notice by his or her employer to be on standby or otherwise responsible for performing tasks related to his or her employment either at the employer’s premises or other previously designated location by his or her employer or supervisor to perform a work-related task.
