510.

 (a) Eight hours of labor constitutes a day’s work. Any work in excess of eight hours in one workday and any work in excess of 40 hours in any one workweek and the first eight hours worked on the seventh day of work in any one workweek shall be compensated at the rate of no less than one and one-half times the regular rate of pay for an employee. Any work in excess of 12 hours in one day shall be compensated at the rate of no less than twice the regular rate of pay for an employee. In addition, any work in excess of eight hours on any seventh day of a workweek shall be compensated at the rate of no less than twice the regular rate of pay of an employee. Nothing in this section requires an employer to combine more than one rate of overtime compensation in order to calculate the amount to be paid to an employee for any hour of overtime work. The requirements of this section do not apply to the payment of overtime compensation to an employee working pursuant to any of the following:

(1) An alternative workweek schedule adopted pursuant to Section 511.

(3) An alternative workweek schedule adopted pursuant to a collective bargaining agreement pursuant to Section 514.

(4) An alternative workweek schedule to which this chapter is inapplicable pursuant to Section 554.

(b) Time spent commuting to and from the first place at which an employee’s presence is required by the employer shall not be considered to be a part of a day’s work, when the employee commutes in a vehicle that is owned, leased, or subsidized by the employer and is used for the purpose of ridesharing, as defined in Section 522 of the Vehicle Code.

(c) This section does not affect, change, or limit an employer’s liability under the workers’ compensation law.

511.5.

 (a) Notwithstanding Section 511 or any other law or order of the Industrial Welfare Commission, an individual nonexempt employee may work up to 10 hours per workday without any obligation on the part of the employer to pay an overtime rate of compensation, except as provided in subdivision (b), if the employee requests this schedule in writing and the employer approves the request. This shall be referred to as an overtime exemption for an employee-selected flexible work schedule.

(b) If an employee-selected flexible work schedule is adopted pursuant to subdivision (a), the employer shall pay overtime at one and one-half times the employee’s regular rate of pay for all hours worked over 40 hours in a workweek or over 10 hours in a workday, whichever is the greater number of hours. All work performed in excess of 12 hours per workday and in excess of eight hours on a fifth, sixth, or seventh day in the workweek shall be paid at double the employee’s regular rate of pay.

(c) The employer may inform its employees that it is willing to consider an employee request to work an employee-selected flexible work schedule, but shall not induce a request by promising an employment benefit or threatening an employment detriment.

(d) The employee or employer may discontinue the employee-selected flexible work schedule at any time by giving written notice to the other party. The request will be effective the first day of the next pay period or the fifth day after notice is given if there are fewer than five days before the start of the next pay period, unless otherwise agreed to by the employer and the employee.

(e) This section does not apply to any employee covered by a valid collective bargaining agreement or employed by the state, a city, county, city and county, district, municipality, or other public, quasi-public, or municipal corporation, or any political subdivision of this state.

(f) This section shall be liberally construed to accomplish its purposes.

(g) (1) The Division of Labor Standards Enforcement shall enforce this section and shall adopt or revise regulations in a manner necessary to conform and implement this section.

(2) This section shall prevail over any inconsistent provisions in any wage order of the Industrial Welfare Commission.
