Cal. Lab. Code § 204.11
Commission wages paid to any employee who is licensed pursuant to the Barbering and Cosmetology Act (Chapter 10 (commencing with Section 7301) of Division 3 of the Business and Professions Code) are due and payable at least twice during each calendar month on a day designated in advance by the employer as the regular payday. For any employee who is licensed pursuant to the Barbering and Cosmetology Act (Chapter 10 (commencing with Section 7301) of Division 3 of the Business and Professions Code), wages that are paid to that employee for providing services for which such a license is required, when paid as a percentage or a flat sum portion of the sums paid to the employer by the client recipient of such service, and for selling goods, constitute commissions, provided that the employee is paid, in every pay period in which hours are worked, a regular base hourly rate of at least two times the state minimum wage rate for all hours worked in addition to commissions paid. The employee and employer may agree to a commission in addition to the base hourly rate. An employee may be compensated for rest and recovery periods at a rate of pay not less than the employee's regular base hourly rate. Nothing in this section shall be interpreted to limit any rights or remedies otherwise available under state or federal law, including the right to overtime compensation.
