California employers tend to focus on overtime, meal breaks and pay timing. Expense reimbursement often receives far less attention – and that gap is where liability tends to build. A small unreimbursed cost can grow quickly when it affects an entire workforce.
California Labor Code Section 2802 covers workplace expense reimbursement. Under this rule, employers must repay employees for necessary costs that arise directly from doing their jobs. The obligation applies even when the amounts seem minor and extends to remote work, travel, personal devices and required tools.
Common areas where reimbursement claims arise
Many claims come from normal business practices, not wrongdoing. Common problem areas include:
- Mileage for local travel
- Cellphone use for work calls or messages
- Home internet tied to remote duties
- Required tools, uniforms or equipment
Vague or inconsistently applied approval rules can complicate the reimbursement process – but they do not necessarily extinguish an employee’s right to reimbursement under Section 2802 if the expense was necessary.
How employers can build a defensible reimbursement policy
Employers should assess whether employees are paying out of pocket for work-related costs, as they may be required by law to cover necessary expenditures under Section 2802. Supervisors should also understand that failing to act on this knowledge may expose the employer to liability. If a supervisor knows a team member is using personal resources for work, that knowledge can create a duty to cover those costs.
Put reimbursement policies in writing. Spell out which costs qualify, when employees must submit requests and what records they need to retain. Consistent submission forms, prompt review and timely payment can reduce the likelihood of a reimbursement dispute. Regular audits of remote work, vehicle use and device policies can also help.
Early policy review costs less than a later dispute
California’s Private Attorneys General Act lets one aggrieved employee file a civil penalty claim for a Labor Code violation on behalf of other affected workers. That includes an employer’s failure to reimburse necessary work expenses. A single unaddressed gap in a reimbursement policy can therefore create exposure that extends well beyond the original claim.
Reviewing expense policies, training supervisors and establishing clear documentation procedures before a complaint is filed typically costs far less – in time, money and disruption – than addressing a dispute after the fact.
