Under California Labor Code §2802, private employers must reimburse employees for all necessary work-related expenses, including personal cell phone use, mileage, home office costs, and required training. No internal company policy can waive this obligation. Courts have also held that even if you already pay for an unlimited phone plan, your employer still owes you reimbursement for required work use. Keep records of every work expense. #EmployeeRights #CaliforniaLaborLaw #WageAndHour
