How to File a Department of Labor Complaint Against an Employer

You can file a Department of Labor complaint against an employer for free by calling, submitting an online form, mailing a letter, or walking into a local field office. The federal DOL splits the work across specialized agencies, so the first decision is where to send it: unpaid wages and overtime go to the Wage and Hour Division, unsafe conditions go to OSHA, and some issues (final paychecks, vacation pay, state minimum wages above the federal floor) belong with your state labor department instead.

Pick the Right Agency First

Filing with the wrong office doesn’t kill your claim, but it delays everything while your complaint gets rerouted.

The Wage and Hour Division (WHD) handles pay violations. It enforces the Fair Labor Standards Act, which covers the federal minimum wage of $7.25 per hour, overtime at time-and-a-half for hours over 40 in a workweek, recordkeeping, and child labor rules.¹ The WHD also takes complaints under the Family and Medical Leave Act, the Employee Polygraph Protection Act, and prevailing wage laws for federal contractors.²

OSHA handles workplace safety and health. If your employer is exposing you to toxic chemicals without protection, ignoring machine guarding rules, or maintaining conditions likely to cause serious injury, OSHA can inspect the workplace, question employers and employees privately, and require corrections.³

Your state labor department is the right stop for anything federal law leaves alone. Federal law does not require vacation pay, severance, holiday pay, meal breaks, or immediate payment of a final paycheck.⁴ If your last paycheck is late and the regular payday has passed, the state is more likely to help than the federal DOL.⁵ Many states also set a higher minimum wage or their own overtime and paid leave rules that only state agencies enforce.

What to Gather Before You File

A complaint backed by documentation moves faster and produces better results. For a wage complaint, the WHD asks for:⁶

Your name, address, and phone number.
The company’s legal name, its location (which may differ from where you actually work), phone number, and the name of an owner or manager.
The type of work you did and how and when you were paid (cash, check, direct deposit; weekly, biweekly).
Copies of pay stubs, your own records of hours worked, and anything else showing the employer’s pay practices.

Dates matter because of the clock. The FLSA gives you two years from the date you file to recover unpaid wages, extended to three years if the violation was willful, meaning the employer knew they were breaking the law.⁷ Every week you wait is potentially a week of wages you can never recover. For OSHA, the timing rule works differently: the agency generally cannot issue citations for hazards that existed more than six months before the complaint.⁸

One boundary to be aware of: if your employer treats you as an independent contractor, the DOL applies its own economic-reality test rather than accepting the label, so the contractor designation alone does not disqualify you. Immigration status is not a factor. The DOL does not ask, and undocumented workers generally have the same wage and hour rights as other workers.

Filing a Wage Complaint With the WHD

Call 1-866-4-US-WAGE (1-866-487-9243), Monday through Friday, 8:00 a.m. to 4:30 p.m. local time, or submit the online inquiry form.⁹ You can also walk into your nearest WHD field office. There is no fee.¹⁰

The WHD assigns your complaint to a local office. For a smaller issue such as a single missed paycheck or a one-worker dispute, the agency may handle it as a conciliation: a phone call to your employer explaining the law and asking them to pay what they owe. For broader violations affecting multiple workers or involving systematic underpayment, the WHD conducts a full investigation, which can include an on-site audit of payroll records.

Filing a Safety Complaint With OSHA

OSHA takes complaints online, by phone at 1-800-321-OSHA (1-800-321-6742), or by mail, fax, or email to your local area office.⁸

How your complaint is handled depends largely on whether you sign it. A written, signed complaint from a current employee, with enough detail about the hazard, will generally trigger an on-site inspection. Unsigned or anonymous complaints usually get the phone/fax treatment: OSHA calls the employer, describes the alleged hazard, and gives them five business days to respond in writing with corrective actions taken or planned. If the response is adequate, OSHA usually will not inspect.¹¹ If you want the strongest response, sign the complaint.

Confidentiality and Retaliation Protection

Every discussion with the Wage and Hour Division is confidential. The WHD will not disclose your name, the nature of your complaint, or even whether a complaint exists. The exceptions are narrow: when revealing your identity is necessary to pursue the allegation (and only with your permission), or when a court orders disclosure.² OSHA also keeps complainants’ names confidential and will not reveal your identity to your employer.¹¹

Retaliation is illegal. Under the FLSA, no one can fire, demote, cut hours, reduce pay, or otherwise punish an employee for filing a complaint, cooperating with an investigation, or testifying in a proceeding on wage and hour violations.¹² The protection reaches internal complaints made directly to your employer, and most courts have held that even oral complaints are protected. It also covers former employees: a previous employer cannot retaliate against you for filing about your time there.¹³ The OSH Act’s Section 11(c) provides parallel protection for workers who file safety complaints, request an inspection, report a work-related injury, or raise safety concerns with their employer.¹⁴

If retaliation happens, you can file a separate retaliation complaint, but the deadlines are very different. For OSHA-related retaliation, you must file within 30 days of the retaliatory action.¹⁵ That window is extremely tight, so move immediately if your employer takes any negative action after you report a safety concern. For FLSA retaliation, you can file with the WHD or sue on your own, and the same two- or three-year FLSA clock applies. Available remedies include reinstatement, lost wages, and an equal amount in liquidated damages.¹³

What Happens After You File

For wage complaints, the WHD can recover back wages and liquidated damages on your behalf and assess civil money penalties against the employer. Most cases resolve administratively: the investigator determines what’s owed and the employer pays. If the employer refuses, the DOL can sue, and willful violators can face criminal prosecution.²

Timelines vary widely. Simple conciliation cases may resolve in a couple of weeks. Full investigations involving multiple employees and extensive payroll audits can stretch for months. The DOL does not publish guaranteed timelines, and staffing at local offices affects how quickly your case moves. If you haven’t heard anything after several weeks, call the field office handling your complaint for an update.

For safety complaints, OSHA either inspects on-site or runs the phone/fax process described above. If an inspection turns up violations, the employer gets citations with deadlines to fix the hazards, plus potential financial penalties.

Suing on Your Own Instead

A DOL complaint is not your only route for unpaid wages. Under the FLSA, you can file a private lawsuit in federal or state court. If you win, the court awards your unpaid wages plus an equal amount in liquidated damages, effectively doubling your recovery, and the employer must also pay your reasonable attorney’s fees and court costs.¹⁶

There is one critical catch. If the Secretary of Labor files a lawsuit on your behalf, your right to bring your own private action for the same wages ends.¹⁶ If you are considering hiring an attorney, decide relatively early. Many wage and hour attorneys work on contingency, typically charging 25% to 45% of the recovery, so upfront cost is not always a barrier. The same two- or three-year statute of limitations applies to private lawsuits as to DOL complaints.⁷
