Cal. Lab. Code § 1182.5

(a) The Legislature finds that the time permitted the Industrial Welfare Commission to consider daily overtime compensation petitions that are to be given priority attention by the commission pursuant to Section 20 of Chapter 1083 of the Statutes of 1980, has created unanticipated delays in the review and possible modification of applicable commission orders for preexisting workweek arrangements, as defined in subdivision (b). The Legislature finds further that legislation is necessary to provide redress of hardships resulting from these unanticipated delays by the enactment of special commission review procedures that augment, and do not limit in any way, the rights and privileges of parties before the Industrial Welfare Commission under this chapter.
(b) For purposes of this section only, a “preexisting workweek arrangement” is defined as, and limited to, a workweek arrangement that existed before November 1980, and had to be modified or abandoned by an employer because the workweek arrangement did not qualify for any exemption provided by the Industrial Welfare Commission from its daily overtime requirements for collectively bargained arrangements, and did not otherwise comply with the daily overtime requirements of an applicable commission order.
(c) An employer who has had in operation an established preexisting workweek arrangement may, prior to July 1, 1985, file a verified petition with the commission for review and modification of an applicable order and, upon filing this petition, shall simultaneously file a copy with the Labor Commissioner. Upon receipt of the petition by the Labor Commissioner a stay of enforcement of the applicable commission order as it would affect the workweek arrangement shall take effect. The Labor Commissioner may reject a petition that, on its face, cannot qualify as a preexisting workweek arrangement. Within three months of commencement of the stay the Labor Commissioner shall certify the preexisting workweek arrangement to the commission if, upon examination, the Labor Commissioner finds that all of the following conditions are met by the workweek arrangement:
1. (1) It was established by the petitioning employer and was in operation prior to November 1980.
2. (2) It had to be abandoned or modified by the employer because of noncompliance with the applicable order of the commission.
3. (3) It was established on a nondiscriminatory basis with the support of affected employees and it continues to have the support of two-thirds of the employees in the covered work group.
4. (4) It complied with all applicable standards of the commission, other than daily overtime requirements.
5. (5) It is found, after consultation with the Director of Industrial Relations when appropriate, not to be adverse to the health and welfare of affected employees.
  In the course of examining a preexisting workweek arrangement and following certification, the Labor Commissioner shall not divert any of the resources of the Division of Labor Standards Enforcement for the purpose of investigating, prosecuting, or otherwise acting upon any alleged violations of the daily overtime provisions of an applicable commission order during any period in 1980 in which a court-issued stay of enforcement was in effect for these provisions; provided, the workweek arrangement involved was in operation during that period in good faith reliance by the employer upon the court-issued stay of enforcement and with the approval of two-thirds of the employer’s affected employees.
(d) In the course of examining a petition for certification to the commission, the Labor Commissioner shall have access to all pertinent records of the petitioning employer and shall have the authority to converse with affected employees of the employer without the presence of management. Until the commission takes action on a petition, the Labor Commissioner shall retain the authority to withdraw a certification to the commission for cause.
(e) Upon receipt by the commission of the Labor Commissioner’s certification of a preexisting workweek arrangement, the stay of enforcement shall continue as hereinafter provided beyond the three-month period for certification until modified or rescinded by the commission. The modification or rescission shall not be made without an appropriate hearing and findings regarding the applicable order. If the commission undertakes review of the applicable order, the stay of enforcement shall continue through the review process and until any resulting modification of the applicable order, in which case, the modified order shall become applicable to the preexisting workweek arrangement.
