What to do if…
you realise you have been underpaid for the last pay period

Short answer

Confirm the missing amount (hours/rate/overtime/deductions), report it to payroll/your manager immediately, and put the request in writing with a specific correction date.

Do not do these things

Do not assume it will fix itself next payday without written confirmation of the amount and the correction date.
Do not sign a “waiver,” pay adjustment, or new pay-rate document you do not understand while you’re upset or rushed.
Do not turn it into a public fight (social media/company-wide posts) before you’ve documented the facts.
Do not accept “cash back”, informal IOUs, or anything that avoids a proper payroll correction and pay stub record.
Do not quit or stop showing up as your first move (unless you are unsafe); it can make a clean resolution harder.

What to do now

Do a fast, focused check of the last pay period.
Compare your pay stub to your records: hours worked, hourly rate or salary basis, overtime, tips/commissions/bonuses, and deductions. Write down the exact shortfall and the pay period dates.
Capture proof (only what’s yours).
Save your pay stub, timecards, schedules, clock-in/out screenshots, and any written approvals for shifts/overtime. Keep copies for your own records, but do not take confidential company information that is not about your pay/time and not yours to keep.
Report it the same day if possible (payroll/HR/manager).
Keep it short and specific: “My paycheck for the period ending [date] appears short by $X (missing Y hours at $Z / overtime / etc.). Please confirm the corrected calculation and when it will be paid.”
Ask for a clear correction plan (not a vague promise).
Request in writing:
- the corrected calculation
- whether they can issue the correction sooner than the next scheduled payday, and the exact date/method they’ll use
- confirmation your pay stub will be corrected so taxes/deductions are accurate
If you don’t get a prompt answer, escalate internally in writing.
Send a brief escalation to HR/payroll leadership: attach the pay stub and your supporting records, and restate what you believe you’re owed and by when.
If it’s still not being fixed, contact wage enforcement.
You can contact the U.S. Department of Labor Wage and Hour Division (WHD) to ask about filing a complaint and next steps. You can call 1-866-487-9243 to be directed to the nearest WHD office. Many states also have their own unpaid-wage process; the right option depends on your state and situation.
Protect yourself from retaliation: document anything that changes after you raise it.
If your hours are cut, you’re threatened, or punished after raising pay concerns, write down dates/times/what happened and save any messages. Retaliation for inquiring about pay, asserting wage rights, or cooperating with an investigation can be prohibited under laws WHD enforces.

What can wait

You do not need to decide today whether to hire a lawyer or sue.
You do not need to audit every paycheck right now — start with the last pay period and stabilise that first.
You do not need to resign or make major career decisions while you’re in the first wave of stress.

Important reassurance

A short paycheck can be scary, especially when bills are due. Many underpayments are correctable payroll errors once you present clear numbers and records. Your best first move is calm documentation plus a written request for a specific correction date.

Scope note

This is first-steps-only guidance to stabilise the situation and prevent costly mistakes. If the underpayment repeats, involves overtime/minimum wage issues, or you face retaliation, you may need specialized advice for your state and job type.

Important note

This is general information, not legal advice. Wage rules and deadlines can differ by job type and state. If you face retaliation, are close to a deadline, or the amount is significant, get independent advice promptly before taking irreversible steps.
