In California, an employee is entitled to be reimbursed by his or her employer “for all the necessary expenditures or losses incurred by the employee in direct consequence of the discharge of his or her duties…”
When working from home, if not normally part of the job, certain expenditures may be entitled to re-imbursement by the employer. For example, if an employee is required to print and mail letters, the cost of stamps and printer ink may be the responsibility of the employer and an employee may be entitled to reimbursement.
