An employer must provide wage statements complying with Labor Code section 226 when an employee’s principal place of work is in California, which ordinarily means the employee works a majority of the time in California. For interstate transportation workers and others who do not spend a majority of their working time in any one state, this test is satisfied when California serves as their base of work operations. This decision rejects the contentions that (a) applicability of California’s wage and hour laws turns on the employer’s location and (b) wage stateements are required for the portion of the time employees work in California even when their principal place of work is in other states. The same territorial limits apply to Labor Code 204 which requires payment of all wages twice a month.
