California requires “indemnity” for necessary expenses incurred by the employee for work purposes, which means the employer must reimburse the employee for expenses incurred for purchasing work related items. For example, an employee that is required to purchase kitchen utensils to perform her job duties must be reimbursed for those expenses. An employee that is required to use their personal cell phone for work is entitled to reimbursement for expenses incurred by the employee for such cell phone use, including reimbursement for the employee's phone bill. Mileage incurred by the use of one's personal vehicle qualifies for reimbursement under Labor Code section 2802. If you have not been provided payment for expenses such as these, you may be entitled to money from your employer or former employer for these costs.
