Cal. Bus. & Prof. Code § 19455
(d) Except as provided in subdivision (e), the board shall oversee the conduct of a union recognition procedure for backstretch employees under the following conditions:
(6) For the purposes of this article:
(7) There are four election units created and recognized pursuant to this section, as follows:
(D) Backstretch employees working for trainers of harness horses stabled at licensed racetracks, including fairs and approved auxiliary training facilities in the northern zone.
The board shall use the California State Mediation and Conciliation Service for all appropriate purposes of this act, including operations related to the conduct of recognition procedures and elections.
(8)
(A) With respect to backstretch workers, a labor organization seeking recognition as the collective bargaining agent for these workers shall collect signed cards indicating individual worker’s intent to be represented by that organization for collective bargaining purposes and submit those cards to the California State Mediation and Conciliation Service for review and validation. When the labor organization is in receipt of cards signed by workers equaling at least 30 percent of the employees in an election unit described in paragraph (4), the California State Mediation and Conciliation Service shall conduct a secret ballot election with respect to the election unit as soon as is practicable thereafter, but in no event more than 30 calendar days after validation by the service of the cards.
Those backstretch employees entitled to vote in the election shall be those who appear on the licensed trainer’s most recent list described in paragraph (3). However, each employer may update his or her list not more than 72 hours prior to the election. If it is determined by the stewards pursuant to the provisions in paragraph (11), that the employer filed an inaccurate or erroneous list with a willful intention to manipulate the results of an election, and that the inaccuracy or error may have affected the outcome of the election, the stewards shall decree that the employer lost the election, regardless of the actual outcome thereof, and the stewards shall issue an order to the trainer to negotiate with the union.
