AMENDMENT TO HOUSE BILL 3762

AMENDMENT NO. ______. Amend House Bill 3762 by replacing everything after the enacting clause with the following:

"Section 1. Short title. This Act may be cited as the Workplace Extreme Temperature Safety Act.

Section 5. Findings. The General Assembly finds and declares:

(a) As the frequency of extreme weather events continues to grow, workers are at an increased risk of serious injury or death. Heat stress or cold stress can occur at temperatures as low as 40 degrees Fahrenheit or as high as 78 degrees Fahrenheit, depending on the working conditions. Unaddressed, heat stress and cold stress can cause a range of serious conditions, including stroke and death if not treated properly. Heat-related injuries and fatalities may be underreported as heat stress exacerbates existing health problems, such as asthma, kidney failure, and heart disease, leading to potential comorbidities being reported. Workers in agriculture and construction are at the highest risk of weather-related injuries, but the problem affects all workers exposed to extreme temperatures, including indoor workers without adequately climate-controlled environments or appropriate personal protective equipment.

(b) From 1979 to 2022, more than 14,000 Americans have died directly from heat-related causes, according to the United States Environmental Protection Agency.

(c) In the absence of a temperature stress standard adopted by the federal Occupational Safety and Health Administration, the Department should adopt extreme temperature safety standards.

Section 10. Definitions. In this Act:

"Acclimatization" means the body's temporary adaptation to work in heat that occurs as a person is exposed to extreme temperature over a period of 7 to 14 days, depending on the amount of recent work in extreme heat and other factors, and may be lost after 7 consecutive days away from working in the extreme heat.

"Cold stress" means the net heat loss a worker experiences due to the combined effects of metabolic heat production, environmental conditions, and clothing, resulting in a drop in body temperature.

"Cold-related illness" means a medical condition resulting from the body losing heat faster than it can produce heat, creating a risk of severe injury, illness, or death.

"Department" means the Department of Labor.

"Director" means the Director of Labor or the Director's designee.

"Employ" means to suffer or to permit to work, unless an individual:

(1) has been and will continue to be free from control and direction over the performance of the individual's work, both under the individual's contract of service with the employer and in fact;

(2) performs work that is either outside the usual course of business or is performed outside of the places of business of the employer, unless the employer is in the business of contracting with parties for the placement of employees; and

(3) is in an independently established trade, occupation, profession, or business.

"Employee" means any individual employed by an employer. For the purposes of this Act, an individual who has contracted for employment with a day and temporary labor service agency and assigned to a third-party client of the day and temporary labor service agency, as those terms are defined in Section 5 of the Day and Temporary Labor Services Act, is considered an employee of both the day and temporary labor service agency and the third-party client.

"Employer" means any individual, partnership, association, or corporation, or instrumentality thereof, acting directly or indirectly in the interest of an employer in relation to an employee. "Employer" includes any day and temporary labor service agency and third-party client, as those terms are defined in Section 5 of the Day and Temporary Labor Services Act.

Section 30. Retaliation.

(a) It is a violation of this Act for an employer, or any agent of an employer, to retaliate against an employee by terminating the employment, disciplining, or taking any other adverse action against any employee for exercising any right under this Act. There shall be a rebuttable presumption of unlawful retaliation under this Section if an employer takes an adverse action against an employee within 90 days after the employee exercises the employee's rights under this Act.

(b) It is a violation of this Act for an employer to retaliate or take adverse action against an employee if the employee:

(1) makes a complaint or threatens to make a complaint to an employer, to a co-worker, to a community organization, before a public hearing, or to a State or federal agency that rights under this Act have been violated;

(2) seeks assistance or intervention with respect to temperature-related health symptoms from the employer, local emergency services, the federal government, the State, or a unit of local government;

(3) refuses to work if the employee reasonably believes:

(A) that an employer has not met the minimum requirements under this Act to prevent illness and injury; or

(B) that performing the required work in extreme temperature conditions may result in illness or injury;

(4) participates in or attempts to participate in a worker safety committee;

(5) uses or attempts to use wearable heat stress monitors;

(6) institutes any proceeding under or related to this Act; or

(7) testifies or prepares to testify in an investigation or proceeding under this Act.

Section 35. Violations. The Department, or the Attorney General pursuant to its authority under Section 6.3 of the Attorney General Act, may issue a temporary emergency cease and desist order to halt any conduct of the employer that is warranted by public health and safety concerns or violates this Act. The Attorney General shall seek a court order extending any emergency cease and desist order to halt any conduct of the employer that is warranted by the public health and safety concerns described in this Act as soon as practicable. Before issuing a cease and desist order authorized under this Section, the Attorney General shall provide notice to the Director.

Section 40. Penalties.

(a) An employer who violates any provision of this Act or any rule adopted under this Act shall be subject to a civil penalty of not less than $100 and not more than $5,000 for each violation found in an initial investigation by the Department or determined by a circuit court in a civil action brought either by an interested party or by the Attorney General pursuant to its authority under Section 6.3 of the Attorney General Act.

(b) An employer found by the Department or a circuit court to have committed a subsequent violation of this Act within 3 years after the first finding shall be subject to a civil penalty of not less than $250 and not more than $15,000 for the violation.

(b-5) For purposes of this Section, each violation of this Act for each employee and for each day the violation continues shall constitute a separate and distinct violation. Any penalty assessed under this Act against a corporation, partnership, limited liability company, or sole proprietorship shall be effective against any successor entity that: (i) is engaged in the same or equivalent trade or activity; and (ii) has one or more of the same principals or officers, as the corporation, partnership, limited liability company, or sole proprietorship against which the penalty was assessed. In determining the appropriateness of a penalty against an employer, the Director or circuit court shall consider factors such as the history of violations by the employer, the seriousness of the violation, the good faith of the employer, and the size of the employer's business. The amount of the penalty may be: (i) recovered in a civil action brought by the Director in any circuit court, represented by the Attorney General; or (ii) ordered by the court, in an action brought by any party, including the Attorney General, for a violation of this Act.

(c) For any violation determined by the Department or circuit court to be willful that occurs within 3 years of an earlier violation, employers shall be subject to civil penalties up to double the amounts specified in subsections (a) and (b).

(d)(1) In any enforcement action under this Act where no employee suffered injury or illness, an employer may assert as an affirmative defense that:

(A) the employer was making good faith efforts to comply with the requirements of this Act;

(B) the violation was minor, technical, or inadvertent in nature;

(C) the employer had implemented and was maintaining a temperature-related illness and injury prevention plan as required under Section 25;

(D) the employer promptly corrected the violation upon discovery or notification; and

(E) the employer has no history of repeated or willful violations of this Act.

(2) If an employer successfully establishes each element of the affirmative defense under paragraph (1), the Director may:

(A) issue a warning instead of a civil penalty;

(B) reduce the civil penalty to a nominal amount; or

(C) require corrective action with a reasonable compliance period instead of an immediate civil penalty.

(3) The defense provided under this subsection does not apply to:

(A) violations that result in employee injury, illness, or death;

(B) willful or repeated violations;

(C) violations involving failure to implement any temperature-related illness and injury prevention plan;

(D) a violation of Section 30; or

(E) situations where the employer failed to correct a violation after receiving notice from the Department.

(4) The burden of proving a defense under this subsection rests with the employer.

Section 45. Enforcement.

(a) The Department shall enforce the provisions of this Act when, in the Department's judgment, there is cause and there are sufficient resources for investigation. The Department shall have the authority to conduct investigations in connection with the administration and enforcement of this Act. The Director or the Director's designee may:

(1) enter and inspect the place of business of any employer for the purpose of examining and inspecting the employer's physical workplace;

(2) inspect or copy any records of the employer that relate in any way to or have a bearing upon the question of compliance with this Act;

(3) question any employee outside the presence of the employer or any employer representative;

(4) access relevant records and work sites where employees are exposed to extreme temperatures, including sites with varying employer arrangements;

(5) conduct any tests at the employer's place of business to determine if this Act has been violated; and

(6) require any employer to submit written statements, including sworn statements, relating to compliance with this Act as the Director may deem necessary or appropriate.

(b) A representative of the employer and a non-managerial representative of the employees shall be given an opportunity to accompany the Department during the physical inspection of any workplace for the purpose of aiding the inspection.

The Department may permit additional representatives of the employer and non-managerial representatives of the employees to be present during the inspection if the Department determines that the additional representatives will aid the inspection. A different employer and non-managerial employee representative may be present during each phase of the inspection if doing so does not interfere with the inspection.

The Department may resolve all disputes as to who shall be the representative of the employer and the non-managerial representative of the employees for purposes of this Act. If there is no authorized representative of the employees, or if the Department is unable to determine with reasonable certainty who the representative of the employees is, the Department shall consult with a reasonable number of employees concerning matters of safety and health in the workplace.

The representative of the employees may be an employee of the employer or a third party. When the representative of the employees is not an employee of the same employer, the representative of the employees may be present during the inspection.

The Department may deny the right to be present during an inspection to any person whose conduct interferes with a fair and orderly inspection.

(c) The Director may compel, by subpoena, the attendance and testimony of witnesses and the production of books, payrolls, records, papers, and other evidence in any investigation or hearing and may administer oaths to witnesses.

(d) The Department shall conduct hearings in accordance with the Illinois Administrative Procedure Act upon written complaint by an investigator of the Department or any interested party of a violation of this Act. After the hearing, if supported by the evidence, the Department may:

(1) issue and cause to be served on any party an order to cease and desist from further violation of this Act;

(2) take affirmative or other action as deemed reasonable to eliminate the effect of the violation; and

(3) determine the amount of any civil penalty allowed by this Act.

(e) If an employee or interested party complaint is the basis for an investigation or inspection conducted by the Director, the identity of the employee or interested party that made the complaint shall be treated as confidential unless the complainant consents to disclosure of the complainant's identity.

(f) If the Director investigates, then the Director shall provide a written report to the complainant within a reasonable time after the investigation has concluded.

Section 50. Review under Administrative Review Law. Any party to a proceeding under this Act may apply for and obtain judicial review of an order of the Department entered under this Act in accordance with the provisions of the Administrative Review Law and the Department in proceedings under this Act may obtain an order from the court for the enforcement of its order.

Section 55. Contempt. If it appears that an employer has violated a valid order of the Department issued under this Act, then the Director may commence an action and obtain from the court an order commanding the employer to obey the order of the Department or be adjudged guilty of contempt of court and punished accordingly.

Section 60. Action for civil enforcement by an interested party.

(a) Upon a reasonable belief that an employer covered by this Act is in violation of any part of this Act, an interested party may initiate a civil action in the county where the alleged offenses occurred or where any party to the action resides, asserting that a violation of this Act has occurred, pursuant to the following sequence of events:

(1) The interested party submits to the Department a complaint describing the violation and naming the employer alleged to have violated this Act.

(2) The Department sends notice of the complaint to the named parties alleged to have violated this Act and any interested party.

(3) The named party may either contest the alleged violation or attempt to cure the alleged violation within 30 days after the receipt of the notice of the complaint. If the named party does not respond within 30 days after the receipt of the notice of the complaint, the Department shall issue a notice of the right to sue to the interested party as described in paragraph (4).

(4) The Department issues a notice of the right to sue to the interested party, if one or more of the following has occurred:

(A) the named party has not cured the alleged violation to the satisfaction of the Director;

(B) the Director has determined that the allegation is unjustified or that the Department does not have jurisdiction over the matter or the parties; or

(C) the Director has determined that the allegation is justified or has not made a determination, and either has decided not to exercise jurisdiction over the matter or has concluded administrative enforcement of the matter.

(b) If, within 180 days after service of the notice of the complaint to the parties, the Department has not (i) resolved the contest and cure period, (ii) with the mutual agreement of the parties, extended the time for the named party to cure the violation and resolve the complaint, or (iii) issued a right to sue letter, the interested party may initiate a civil action for penalties. The parties may extend the 180-day period by mutual agreement. The limitations period for the interested party to bring an action for the alleged violation of the Act shall be tolled for the 180-day period and for the period of any mutually agreed extensions. At the end of the 180-day period or any mutually agreed extensions, the Department shall issue a right to sue letter to the interested party.

(c) Upon receipt of a right to sue letter from the Department, an interested party may bring a civil action, in the name of the State or for the benefit of any impacted employee, in the county where the alleged offenses occurred or where any party to the action resides. If the civil action is brought in the name of the State:

(1) No later than 30 days after filing the action, the interested party shall serve upon the State through the Attorney General a copy of the complaint and written disclosure of substantially all material evidence and information the interested party possesses.

(2) The State may elect to intervene and proceed with the action no later than 60 days after it receives both the complaint and the material evidence and information. The State may, for good cause shown, move the court for an extension of the time to intervene and proceed with the action.

(3) Before the expiration of the 60-day period or any extensions under subparagraph (2), the State shall:

(A) proceed with the action, in which case the action shall be conducted by the State; or

(B) notify the court that it declines to take the action, in which case the interested party bringing the action shall have the right to conduct the action.

(4) When the State conducts the action, the interested party shall have the right to continue as a party to the action subject to the following limitations:

(A) the State may dismiss the action notwithstanding the objections of the interested party initiating the action if the interested party has been notified by the State of the filing of the motion and the court has provided the interested party with an opportunity for a hearing on the motion; and

(B) the State may settle the action with the defendant notwithstanding the objections of the person initiating the action if the court determines, after a hearing, that the proposed settlement is fair, adequate, and reasonable under all the circumstances.

(5) If an interested party brings an action under this Section, no person other than the State may intervene or bring a related action on behalf of the State based on the facts underlying the pending action.

(6) An action brought in court by an interested party under this Section may be dismissed if the court and the Attorney General give written consent to the dismissal and their reasons for consenting.

(d) Any claim or action filed by an interested party under this Section shall be made no later than 3 years after the alleged conduct resulting in the complaint, plus any period for which the limitations period has been tolled.

(e) In an action brought by an interested party under this Section, an interested party may recover against the covered entity any statutory penalties set forth in Section 40, injunctive relief, and any other relief available to the Department. An interested party who prevails in a civil action shall receive 10% of any statutory penalties assessed, plus any attorney's fees and costs. The remaining 90% of any statutory penalties assessed shall be deposited into a special fund of the Department for enforcement of this Act.

Section 65. Private right of action.

(a) An employee aggrieved by any violation of this Act or any rule adopted under this Act may file suit in circuit court, in the county where the alleged offense occurred or where any employee who is party to the civil action resides, without regard to exhaustion of any alternative administrative remedies provided in this Act. A civil action may be brought by one or more employees for and on behalf of themselves and other employees similarly situated. An employee whose rights have been violated under this Act by an employer is entitled to collect:

(1) in the case of a notice violation, statutory damages in an amount of not less than $50 and not more than $500 for the violation of this Act;

(2) in the case of a health and safety violation, in addition to all other relief available for injury, compensatory damages and an amount of statutory damages of not less than $50 and not more than $500 for each violation of this Act;

(3) in the case of unlawful retaliation, all relief necessary to make the employee whole, including, but not limited to:

(A) permanent or preliminary injunctive relief;

(B) reinstatement with the same seniority status that the employee would have had, but for the violation;

(C) back pay, with interest of 9% per annum for no more than 90 calendar days after the date the complaint is filed, and front pay;

(D) liquidated damages of up to $10,000;

(E) compensation for any costs incurred as a result of the violation, including litigation costs, expert witness fees, and reasonable attorney's fees; and

(F) a civil penalty of $10,000, payable to the employee.

(b) The right of an aggrieved employee to bring an action under this Section terminates 3 years after the date of the violation. This limitations period is tolled if an employer or prospective employer has failed to provide an employee or prospective employer information required under this Act or has deterred an employee or prospective employee from the exercise of rights under this Act.

(c) Nothing in this Section shall be construed to limit an employee's rights to bring an action for injury through a tort action, workers compensation, union grievance procedure, or any other legal avenue available to an employee.

(d) Notwithstanding any other provision of this Section, an employee of a small employer may not bring a civil action under this Section. An employee of a small employer retains all rights to file a complaint with the Department under Section 45 and to benefit from enforcement actions brought by the Department or an interested party under Sections 45 and 60.

Section 70. No diminution of obligations.

(a) No provision of this Act or any rules adopted under this Act shall be construed as:

(1) requiring an employer to diminish or reduce protections that are provided by the employer under an employer policy or collective bargaining agreement and that either are more favorable to employee safety than the protections required by this Act or provide rights or benefits to employees not provided by this Act;

(2) prohibiting an employer from agreeing to provide under an employer policy or collective bargaining agreement protections that are more favorable to employees than the protections required by this Act or prohibiting an employer from agreeing to provide rights or benefits to employees not provided by this Act;

(3) superseding any law providing collective bargaining rights for employees or in any way reducing, diminishing, or adversely affecting those collective bargaining rights or the obligations of employers under any law; or

(4) limiting the alternative compliance mechanisms available to employers under Section 75.

(b) To the extent any federal temperature safety law, rule, or regulation is more favorable to employees than any requirement of this Act, the Director shall update the extreme temperature safety standard rules adopted under this Act to align with the federal standard.

Section 75. Alternative compliance mechanisms.

(a) Where a collective bargaining agreement is in effect that specifically addresses temperature-related safety conditions, the provisions of that agreement shall govern instead of the protocols and work practice requirements established under Section 25, if the agreement expressly addresses, at minimum:

(1) the means by which heat and cold conditions are measured at the worksite and communicated to employees, including the instruments or indices used and the frequency of measurement;

(2) rest break access and frequency under extreme heat and extreme cold conditions;

(3) access to water and to the worksite shade and warming or cooling stations, where applicable;

(4) emergency response procedures for heat-related or cold-related illness; and

(5) where appropriate, personal protective equipment and uniform requirements suited to the temperature conditions employees are likely to encounter, including adjustments to temperature action thresholds or uniform policies for work requiring heavy personal protective equipment or occupational uniforms.

(b) A collective bargaining agreement that does not contain a subject matter required under subsection (a) shall not be deemed to satisfy the requirements of subsection (a) with respect to that subject matter, and the applicable provisions of this Act shall govern. A qualifying collective bargaining agreement may establish temperature action thresholds that differ from those established under Section 10 or adopted by the Director under Section 20. If a collective bargaining agreement expires or is voided, the requirements of this Act shall apply immediately and in full until a successor agreement satisfying the requirements of subsection (a) is in effect.

(c) This Act does not apply to employees covered by a collective bargaining agreement in effect on the effective date of this Act until the expiration of that agreement.

(d) Where a public employer, including a fire protection district organized under the Fire Protection District Act, has adopted and implemented a written temperature safety policy that specifically addresses heat and cold conditions, that policy shall govern in lieu of the protocols and work practice requirements established under Section 25, if the policy expressly addresses, at minimum:

(1) the means by which heat and cold conditions are measured at the worksite and communicated to employees, including the instruments or indices used and the frequency of measurement;

(2) rest break access and frequency under extreme heat and extreme cold conditions;

(3) access to water and, where applicable to the worksite, shade and warming or cooling stations;

(4) emergency response procedures for heat- or cold-related illness;

(5) personal protective equipment and uniform requirement adjustments appropriate to the temperature conditions employees are likely to encounter; and

(6) a mechanism by which employees may report temperature-related safety concerns to a designated employer contact without fear of retaliation.

(e) A public employer policy that does not contain a subject matter required under subsection (d) shall not be deemed to satisfy the requirements of subsection (a) with respect to that subject matter, and the applicable provisions of this Act shall govern. A qualifying public employer policy may establish temperature action thresholds that differ from those established under Section 10 or adopted by the Director under Section 20 where the public employer determines, based on worksite-specific conditions, that different thresholds are appropriate. If a public employer policy is rescinded or expires without a successor policy in effect, the requirements of this Act shall apply immediately and in full.

(f) Where a collective bargaining agreement governs instead of subsection (a) of Section 25, the provisions of Sections 30, 35, 40, 45, 55, 60, and 65 do not apply. Disputes arising under a qualifying collective bargaining agreement shall be resolved through the grievance and arbitration procedures established in that agreement. If a collective bargaining agreement expires or is voided without a successor agreement satisfying the requirements of subsection (a) in effect, the enforcement provisions of this Act shall apply immediately and in full. Where a public employer policy governs under subsection (d), the provisions of Sections 30, 35, 40, 45, 55, 60, and 65 do not apply with respect to the subject matter areas addressed by that policy. If a public employer policy is rescinded or expires without a successor policy in effect, the enforcement provisions of this Act shall apply immediately and in full.

Section 97. Severability. Should one or more of the provisions of this Act be held invalid, the invalidity shall not affect any of the valid provisions hereof.

Section 99. Effective date. This Act takes effect January 1, 2027.".
