California Code, Public Contract Code - PCC § 10510.52

(a) A vendor that supplies the university with employees to perform services, shall provide those employees with written notice of the total compensation rate specified in the vendor's contract with the university or required by university policy, whichever is higher, and the employee's hourly rate of pay and hourly value of employer-provided benefits.  The vendor shall provide employees with these notices at the time each employee is assigned to perform services for the university and thereafter, each January, and within seven days of a change to the employee's hourly rate.

“Basic payroll information pertaining to all employees who accept an assignment or continue performing services for the University of California will be shared with the University of California and the organizations that represent University of California employees.  The information that will be shared includes your full name, university work location, mobile telephone number, email address, and home address.  The purpose of sharing this information is to ensure that the University of California and the organizations that represent University of California employees can contact you if they discover you have been paid less than required by the vendor's contract with the university or university policy and so that the University of California can provide you with a timely offer of employment as soon as you become eligible.”

(c) If an auditor, vendor, the university, or any other person conducts or receives an audit, verification, notice, report, or finding with regard to whether a vendor has compensated employees at the total compensation rate required by the vendor's contract with the university or university policy, including the vendor's failure to provide employees with any “wage and benefits parity” rate required by university policy, that audit, verification, notice, report, or finding shall be provided to the university and members of any joint labor-management committee.
