How unpaid wages and back pay work
If your employer didn't pay you everything the law requires, the difference is back pay. The two most common shortfalls are unpaid overtime and unpaid minimum wage.
Unpaid overtime (FLSA)
Non-exempt employees must be paid 1.5× the regular rate for hours over 40 in a workweek (29 U.S.C. §207). The workweek is a fixed 7-day period and weeks can't be averaged together. If overtime hours were worked entirely off the clock, the full 1.5× is owed; if they were paid at straight time without the premium, the missing 0.5× is owed.
Liquidated damages — the doubling rule
Under 29 U.S.C. §216(b), an employer that violates the overtime or minimum-wage rules is liable for the unpaid wages plus an equal additional amount as liquidated damages — effectively doubling the recovery. In private lawsuits this is presumed; the employer can avoid it only by proving it acted in good faith with reasonable grounds to believe it was complying (§260).
How long you have to file
FLSA claims must generally be filed within 2 years of the violation — 3 years if it was willful (29 U.S.C. §255). Some states allow longer for state-law claims (California 3–4 years; New York 6 years). Every week that passes can shrink what you're able to recover, so don't wait.
Late final paycheck
Many states add penalties when a final paycheck is late — these stack on top of FLSA back pay. California (Labor Code §203) makes wages continue as a penalty at your daily rate for up to 30 days. Texas, New York, Illinois and others have their own rules; a few states (e.g. Florida) have none and the federal rule applies.
How to file a claim
You can file with the U.S. Department of Labor, Wage and Hour Division (dol.gov/agencies/whd) or your state labor agency, and you may also sue privately under §216(b). Keep your own records of hours worked.
FAQ
- How is unpaid overtime calculated?
- 1.5× your regular rate for hours over 40 a week. Fully unpaid hours are owed 1.5×; hours paid at straight time are owed the missing 0.5×.
- What are liquidated damages?
- An equal additional amount on top of the back pay — doubling it — unless the employer proves a good-faith defense.
- How long do I have to file?
- Generally 2 years under the FLSA, 3 if willful; some states allow longer. Waiting reduces what you can recover.
- Does this replace a lawyer?
- No. This is an estimate to help you understand the scale of a possible claim. Talk to a licensed employment attorney or your labor agency.
