Sec. 5.

The Director may provide by regulation for the employment in any occupation of individuals whose earning capacity is impaired by age, or physical or mental deficiency or injury at such wages lower than the minimum wage rate provided in Section 4, subsection (a), as he may find appropriate to prevent curtailment of opportunities for employment, to avoid undue hardship, and to safeguard the minimum wage rate of this Act, except that no person who maintains a production level within the limits required of other employees may be paid at less than the minimum wage. No employee shall be employed at wages fixed pursuant to this Section except under a special license issued under applicable regulations of the Director.

Sec. 6.

(a) For any occupation, the Director may provide by regulation for the employment in that occupation of learners at such wages lower than the minimum wage provided in Section 4, subsection (a) as the Director may find appropriate to prevent curtailment of opportunities for employment and to safeguard the minimum wage rate of this Act.

(c) In any occupation, every employer may pay a subminimum wage to learners during their period of learning. However, under no circumstances, may an employer pay a learner a wage less than 70% of the minimum wage rate provided in Section 4, subsection (a) of this Act for employees 18 years of age or older.

(d) No person is deemed a learner in any occupation for which he has completed the required training; and in no case may a person be deemed a learner in that occupation after 6 months of such training, except where the Director finds, after investigation, that for the particular occupation a minimum of proficiency cannot be acquired in 6 months.

Sec. 7.

The Director or his authorized representatives have the authority to:

(a) Investigate and gather data regarding the wages, hours and other conditions and practices of employment in any industry subject to this Act, and may enter and inspect such places and such records (and make such transcriptions thereof) at reasonable times during regular business hours, not including lunch time at a restaurant, question such employees, and investigate such facts, conditions, practices or matters as he may deem necessary or appropriate to determine whether any person has violated any provision of this Act, or which may aid in the enforcement of this Act.

(b) Require from any employer full and correct statements and reports in writing, including sworn statements, at such times as the Director may deem necessary, of the wages, hours, names, addresses, and other information pertaining to his employees as he may deem necessary for the enforcement of this Act.

Sec. 8.

Every employer subject to any provision of this Act or of any order issued under this Act shall make and keep for a period of not less than 3 years, true and accurate records of the name, address and occupation of each of his employees, the rate of pay, and the amount paid each pay period to each employee, the hours worked each day in each work week by each employee, and such other information and make such reports therefrom to the Director as the Director may by regulation prescribe as necessary or appropriate for the enforcement of the provisions of this Act or of the regulations thereunder. Such records shall be open for inspection or transcription by the Director or his authorized representative at any reasonable time as limited by paragraph (a) of Section 7 of this Act. Every employer shall furnish to the Director or his authorized representative on demand a sworn statement of such records and information upon forms prescribed or approved by the Director. Each worker employed at the learner rate must be designated as such on the payroll record kept by the employer, with the learner's occupation shown.

Sec. 9.

Every employer subject to any provision of this Act or of any regulations issued under this Act shall keep a summary of this Act approved by the Director, and copies of any applicable regulations issued under this Act or a summary of such regulations, posted in a conspicuous and accessible place in or about the premises wherever any person subject to this Act is employed. Employers shall be furnished copies of such summaries and regulations by the State on request without charge.

Sec. 10.

(a) The Director shall make and revise administrative regulations, including definitions of terms, as he deems appropriate to carry out the purposes of this Act, to prevent the circumvention or evasion thereof, and to safeguard the minimum wage established by the Act. Regulations governing employment of learners may be issued only after notice and opportunity for public hearing, as provided in subsection (c) of this Section.

(b) In order to prevent curtailment of opportunities for employment, avoid undue hardship, and safeguard the minimum wage rate under this Act, the Director may also issue regulations providing for the employment of handicapped workers at wages lower than the wage rate applicable under this Act, under permits and for such periods of time as specified therein; and providing for the employment of learners at wages lower than the wage rate applicable under this Act. However, such regulation shall not permit lower wages for the handicapped on any basis that is unrelated to such person's ability resulting from his handicap, and such regulation may be issued only after notice and opportunity for public hearing as provided in subsection (c) of this Section.

(c) Prior to the adoption, amendment or repeal of any rule or regulation by the Director under this Act, except regulations which concern only the internal management of the Department of Labor and do not affect any public right provided by this Act, the Director shall give proper notice to persons in any industry or occupation that may be affected by the proposed rule or regulation, and hold a public hearing on his proposed action at which any such affected person, or his duly authorized representative, may attend and testify or present other evidence for or against such proposed rule or regulation. Rules and regulations adopted under this Section shall be filed with the Secretary of State in compliance with "An Act concerning administrative rules", as now or hereafter amended. Such adopted and filed rules and regulations shall become effective 10 days after copies thereof have been mailed by the Department to persons in industries affected thereby at their last known address.

(d) The commencement of proceedings by any person aggrieved by an administrative regulation issued under this Act does not, unless specifically ordered by the Court, operate as a stay of that administrative regulation against other persons. The Court shall not grant any stay of an administrative regulation unless the person complaining of such regulation files in the Court an undertaking with a surety or sureties satisfactory to the Court for the payment to the employees affected by the regulation, in the event such regulation is affirmed, of the amount by which the compensation such employees are entitled to receive under the regulation exceeds the compensation they actually receive while such stay is in effect.

Sec. 11.

(a) Any employer or his agent, or the officer or agent of any private employer who:

(1) Hinders or delays the Director or his authorized representative in the performance of his duties in the enforcement of this Act; or

(2) Refuses to admit the Director or his authorized representative to any place of employment; or

(3) Fails to keep the records required under this Act or to furnish such records required or any information to be furnished under this Act to the Director or his authorized representative upon request; or

(7) Refuses to furnish a sworn statement of such records or any other information required for the proper enforcement of this Act; or

(8) Fails to post a summary of this Act or a copy of any applicable regulation as required by Section 9 of this Act; shall be guilty of a Class B misdemeanor; and each day of such failure to keep the records required under this Act or to furnish such records or information to the Director or his authorized representative or to fail to post information as required herein constitutes a separate offense.

(b) Any employer or his agent, or the officer or agent of any private employer, who pays or agrees to pay to any employee wages at a rate less than the rate applicable under this Act or of any regulation issued under this Act is guilty of a Class B misdemeanor, and each week on any day of which such employee is paid less than the wage rate applicable under this Act constitutes a separate offense.

(c) Any employer or his agent, or the officer or agent of any private employer, who discharges or in any other manner discriminates against any employee because that employee has made a complaint to his employer, or to the Director or his authorized representative, that he has not been paid wages in accordance with the provisions of this Act, or because that employee has caused to be instituted or is about to cause to be instituted any proceeding under or related to this Act, or because that employee has testified or is about to testify in an investigation or proceeding under this Act, is guilty of a Class B misdemeanor.

(d) It is the duty of the Department of Labor to inquire diligently for any violations of this Act, and to institute the action for penalties herein provided, and to enforce generally the provisions of this Act.

Sec. 12.

(a) If any employee is paid by his employer less than the wage to which he is entitled under the provisions of this Act, the employee may recover in a civil action the amount of any such underpayments together with costs and such reasonable attorney's fees as may be allowed by the Court, and any agreement between him and his employer to work for less than such wage is no defense to such action. At the request of the employee or on motion of the Director of Labor, the Department of Labor may make an assignment of such wage claim in trust for the assigning employee and may bring any legal action necessary to collect such claim, and the employer shall be required to pay the costs incurred in collecting such claim. Every such action shall be brought within 3 years from the date of the underpayment. Such employer shall be liable to the Department of Labor for 20% of the total employer's underpayment and shall be additionally liable to the employee for punitive damages in the amount of 2% of the amount of any such underpayments for each month following the date of payment during which such underpayments remain unpaid. The Director may promulgate rules for the collection of these penalties. The amount of a penalty may be determined, and the penalty may be assessed, through an administrative hearing. The penalty may be recovered in a civil action brought by the Director of Labor in any circuit court. The penalty shall be imposed in cases in which an employer's conduct is proven by a preponderance of the evidence to be willful. In any such action, the Director of Labor shall be represented by the Attorney General.

(b) The Director is authorized to supervise the payment of the unpaid minimum wages and the unpaid overtime compensation owing to any employee or employees under Sections 4 and 4a of this Act and may bring any legal action necessary to recover the amount of the unpaid minimum wages and unpaid overtime compensation and an equal additional amount as punitive damages, and the employer shall be required to pay the costs. The action shall be brought within 5 years from the date of the failure to pay the wages or compensation. Any sums thus recovered by the Director on behalf of an employee pursuant to this subsection shall be paid to the employee or employees affected. Any sums which, more than one year after being thus recovered, the Director is unable to pay to an employee shall be deposited into the General Revenue Fund.

Sec. 13.

Any standards relating to minimum wages, maximum hours, overtime compensation or other working conditions in effect under any other law of this State on the effective date of this Act which are more favorable to employees than those applicable to such employees under this Act or the regulations issued hereunder, are not amended, rescinded, or otherwise affected by this Act but continue in full force and effect and may be enforced as provided by law unless and until they are specifically superseded by standards more favorable to such employees by operation of or in accordance with regulations issued under this Act.

Sec. 14.

Nothing in this Act is deemed to interfere with, impede, or in any way diminish the right of employees to bargain collectively with their employers through representatives of their own choosing in order to establish wages or other conditions of work in excess of the applicable minimum standards of the provisions of this Act.

Sec. 15.

If any provision of this Act or the application thereof to any person, employer, occupation or circumstance is held invalid, the remainder of this Act and the application of such provision to other persons, employers, occupations, or circumstances are not affected thereby.
