The IWC’s wage orders setting minimum wages and the method of calculating hours of work for purposes of paying minimum wages do not apply to the University of California which is not a political subdivision of the state and does not otherwise fall within the definition of a public employer under Wage Order No. 4. Instead, the University is a separate arm of state government that is given constitutional power to govern its own internal affairs, such as the terms on which it employs its workers. So a university employee’s suit claiming the University wrongly counted her hours of work was properly dismissed.
