Here is a list of five rights provided to employees under the California Labor Code that the employee may not waive by agreement with an employer.

1. Minimum wage
Labor Code Section 1194 provides a private right of action to enforce violations of minimum wage and overtime laws. That statute clearly voids any agreement between an employer and employee to work for less than minimum wage or not to receive overtime.

2. Overtime
In Gentry v. Superior Court, the Supreme Court explained:

[Labor Code] Section 510 provides that nonexempt employees will be paid one and one-half their wages for hours worked in excess of eight per day and 40 per week and twice their wages for work in excess of 12 hours a day or eight hours on the seventh day of work. Section 1194 provides a private right of action to enforce violations of minimum wage and overtime laws.

By its terms, the rights to the legal minimum wage and legal overtime compensation conferred by the statute are unwaivable. “Labor Code section 1194 confirms ‘a clear public policy . . . that is specifically directed at the enforcement of California’s minimum wage and overtime laws for the benefit of workers.’"

3. Expense reimbursement
Labor Code section 2802 requires employers to reimburse its employees for “necessary expenditures or losses incurred by the employee” while performing his or her job duties. Labor Code section 2804, clearly provides that an employee cannot waive this right to be reimbursed for or liable for the cost of doing business. Section 2804 provides, “Any contract or agreement, express or implied, made by any employee to waive the benefits of this article or any part thereof, is null and void….”

4. Right to participate in PAGA representative actions
The California Supreme Court recently clarified that employees may not waive their right to bring a representative action under the Private Attorney General Act (PAGA) (even though the Court held that class action waivers in arbitration agreements are enforceable). The Court held in Iskanian v. CLS Transportation that, “we conclude that an arbitration agreement requiring an employee as a condition of employment to give up the right to bring representative PAGA actions in any forum is contrary to public policy.”

5. Right to receive undisputed wages
Under Labor Code section 206.5 employers and employees may not enter into agreements that waive the employee’s right to receive wages that are undisputed. Labor Code section 206.5 also provides that an employer may not require “as a condition of being paid, to execute a statement of the hours he or she worked during a pay period which the employer knows to be false.”
