"Where an employer is out of compliance with this law, applicants and employees will be able to file a complaint with the DLI or file a civil lawsuit against the employer in court.

If applicants or employees file a complaint with the DLI, the DLI may issue a citation and/or notice of assessment and order the employer to pay to the complainant actual damages, double statutory damages (or $5,000, whichever is greater), interest of 1% per month on compensation owed, payment to the department for the costs of investigation and enforcement, and other appropriate relief. The DLI may also order an employer to pay civil penalties in response to complaints, ranging from $500 for a first violation to $1,000 or 10% of damages (whichever is greater) for a repeat violation."
