How to Write a Demand Letter for Unpaid Wages

A demand letter for unpaid wages is a formal written notice to your employer requesting payment of wages you believe you are owed. It gives the employer a chance to pay voluntarily before you escalate to a government complaint or lawsuit. Many wage disputes — especially straightforward overtime shortfalls — are resolved at this stage.

When to send one

A demand letter makes sense when you have a clear, documented claim, the amount is modest relative to the cost of a lawsuit, you want to give the employer an opportunity to correct a genuine error before involving a government agency, or you are still employed and prefer to start with a professional internal resolution. It also creates a paper trail: the employer's response or silence becomes evidence in any subsequent WHD complaint or legal action.

What to include

Your letter should state: your name, job title, and employment dates; the specific type of wages you are owed (overtime, minimum wage, off-the-clock hours); the pay periods covered; the legal basis (refer to the FLSA or your state wage act by name); your calculation — show the arithmetic clearly, line by line, ideally as an attached table; and a firm payment deadline, typically 14 to 21 days.

The back-pay calculator produces a week-by-week underpayment table you can attach directly. A precise number with supporting math is much harder for an employer to dismiss than a vague request for 'what I'm owed.'

Tone and language

State facts plainly and professionally. Something like: 'From [start date] to [end date], I worked an average of [N] hours per week. I was paid for 40 hours at $[rate]. The remaining [N] weekly overtime hours, at 1.5× my regular rate of $[rate × 1.5], total $[X] for this period. I am requesting payment of this amount within 14 days of the date of this letter.' Avoid accusations of fraud or intent — leave that for a later legal filing if needed.

How to send it

Email it with a read receipt and also send a physical copy by certified mail with return receipt requested to the employer's registered business address. This documents both the content and the delivery date. If you address it to HR, copy a direct supervisor or the business owner — disputes can stall at the HR level. Keep copies of everything.

After sending it

If the employer pays or offers a reasonable settlement, great — get any payment agreement in writing before you cash a check. If they ignore the letter or deny the claim, you now have a documented record of their awareness of the dispute. Take that record to the WHD or an employment attorney. If they retaliate — cutting hours, changing your schedule, or terminating you — that is a separate FLSA violation; report it immediately.
