Such programs shall be operated and implemented pursuant to statutes enacted by or in accordance with the provisions of the Prison Inmate Labor Initiative of 1990, and by rules and regulations prescribed by the Director of Corrections and, for county jail programs, by local ordinances.

(b) No contract shall be executed with an employer that will initiate employment by inmates in the same job classification as non-inmate employees of the same employer who are on strike, as defined in Section 1132.6 of the Labor Code, as it reads on January 1, 1990, or who are subject to lockout, as defined in Section 1132.8 of the Labor Code, as it reads on January 1, 1990. Total daily hours worked by inmates employed in the same job classification as non-inmate employees of the same employer who are on strike, as defined in Section 1132.6 of the Labor Code, as it reads on January 1, 1990, or who are subject to lockout, as defined in Section 1132.8 of the Labor Code, as it reads on January 1, 1990, shall not exceed, for the duration of the strike, the average daily hours worked for the preceding six months, or if the program has been in operation for less than six months, the average for the period of operation.

(c) Nothing in this section shall be interpreted as creating a right of inmates to work.
