While California labor laws primarily apply to instate workers, certain scenarios can extend these protections to outofstate employees. Oncall work is considered hours worked under the State Law.There is no Pennsylvania labor law which requires an employer to pay an employee not to work. If an employee is on call, that time is compensable. Some states set stricter oncall pay laws. For example, California on-call laws extend to employees calling in to find out if they have to work. Pennsylvania minimum wage laws require employers to compensate employees for all hours worked. "Hours worked" includes all time an employee must be on duty, or on the employer's premises or at any other prescribed place of work. No federal or California laws prevent employers from requiring nonstandard work schedules in an employment contract. In California, hourly and nonexempt employees have to clock in and out of work.
