How to Recover Unpaid Wages: DOL (US) and HMRC (UK) Complaint Process
UNITED STATES
US DOL Wage and Hour Division: Step-by-Step
Document Your Hours and Pay
Before filing, gather all records you have: payslips, bank statements showing deposits, any text messages or emails about scheduled hours, handwritten time logs, screenshots of scheduling apps. You do not need a complete record to file a complaint -- the DOL investigator will gather employer records -- but the more documentation you have, the stronger your case.
File a Complaint with the Wage and Hour Division
File online at dol.gov/agencies/whd/contact/complaints, by phone at 1-866-487-9243 (free, confidential), or in person at your nearest WHD district office. There is no filing fee. Complaints are confidential by law -- your employer cannot be told you filed unless you consent. You can also file an anonymous tip.
The WHD Investigates
An investigator contacts the employer, reviews payroll records, interviews employees (confidentially), and determines if violations occurred. This can take weeks to months depending on complexity and caseload.
What You Can Recover
Back wages (the underpaid amount) plus liquidated damages of an equal amount -- effectively doubling your recovery. Liquidated damages are automatic unless the employer proves it acted in good faith and had objectively reasonable grounds for believing its pay practices were lawful. Attorney fees may also be recoverable in litigation.
Statutes of Limitations
Standard FLSA violation: 2 years from the date wages were owed. Willful violation (employer knew it was violating the law): 3 years. Many states have longer statutes -- California allows 3-4 years for minimum wage claims.
FLSA COLLECTIVE ACTION
Multiple Workers Can File Together
FLSA section 216(b) allows workers to bring a "collective action" -- a lawsuit where one or more workers sue on behalf of themselves and similarly situated colleagues. Unlike a class action (which is opt-out), an FLSA collective action requires each additional worker to affirmatively opt in. If your employer has underpaid multiple workers in the same way (e.g., failing to pay for pre-shift time, applying an illegal deduction), a collective action can make it economical for lawyers to take the case and maximise recovery. Many employment law firms take FLSA collective actions on contingency.
State-Level Remedies (Often Better Than Federal)
| State | Enhanced Remedy | Statute of Limitations |
|---|---|---|
| California | Attorneys' fees mandatory; civil penalties $100-250/worker/pay period; Wage Theft Prevention Act requires pay stubs with 9 specific items | 3 years (Labor Code 1194) |
| New York | Liquidated damages 200% (not 100%); attorneys' fees; NY WTPA requires detailed wage notices | 6 years |
| Washington | Double damages plus attorneys' fees; employees can file directly with L&I without a lawyer | 3 years |
| Massachusetts | Triple damages for wage theft; attorney general referrals common | 3 years |
| Federal (FLSA) | Back wages + 100% liquidated damages + attorneys' fees (if employer had no good faith defence) | 2 years (3 years willful) |
UNITED KINGDOM
UK HMRC National Minimum Wage Enforcement
Contact HMRC NMW Helpline
Phone: 0300 123 1100. Online complaint form: gov.uk/pay-and-work-rights. Anonymous complaints are accepted. Available in Welsh. HMRC's National Minimum Wage Compliance team handles all NMW complaints separately from your employer's regular tax affairs.
HMRC Investigates the Employer
HMRC sends compliance officers to inspect employer payroll records, interview workers, and review time records. Employers are required to keep adequate pay records for at least 3 years. Workers may be interviewed confidentially.
Notice of Underpayment
If HMRC finds a violation, it issues a Notice of Underpayment. The employer must repay all arrears to the worker within 28 days and pay a civil penalty of 200 percent of the arrears to HMRC (capped at £20,000 per worker affected). For persistent or deliberate underpayers, criminal prosecution is possible.
Public Naming Scheme
Employers found to have underpaid the NMW are publicly named on the government's Naming and Shaming scheme, published twice per year. Since 2013 over 3,000 employers have been named. Named employers must also pay the arrears and penalty.
FOR WORKERS
What to Document Before You Leave a Job
- Keep copies of all payslips
- Screenshot or save digital pay statements
- Keep a personal log of hours worked (start/end times)
- Screenshot scheduling apps before they expire
- Keep any written rotas, schedules, or WhatsApp shifts
- Save emails confirming hours or shift patterns
- Note any deductions from pay with dates
- Keep copies of your employment contract and any handbooks
FOR EMPLOYERS
Proactive Compliance Saves Money
The cost of back wages plus liquidated damages plus legal fees in a wage dispute almost always exceeds the cost of proper payroll from the start. If you are running payroll for hourly workers across multiple states, consider payroll software that auto-applies each state and city's current minimum wage.
