Annotated letter structure
1. Identify yourself and your employer
Use your full name and mailing address, then identify the employer and the person responsible for payroll or HR.
2. State how and when the job ended
Give your last day worked and say whether you were fired, laid off, or resigned; that fact determines the Illinois deadline.
3. List the unpaid wages
Identify unpaid regular wages, overtime, commissions, bonuses, vacation, or expenses separately when they apply. If the amount is uncertain, demand all earned wages due.
4. Cite the applicable deadline
State the applicable timing rule and cite 820 ILCS 115/5 without claiming that every exception has been resolved.
5. Make a clear payment demand
Ask for the full amount due by a clear date and explain that you may contact the wage agency if the issue remains unresolved.
6. Preserve proof of delivery
Keep the PDF, sent email, postal receipt, tracking result, and any reply together with your wage records.
After you finish the letter
Save the signed letter as a PDF. Send it to a person responsible for payroll or HR, keep the sent email, and consider Certified Mail with Return Receipt for a separate delivery record.
If the response date passes, review the filing instructions from the Illinois Department of Labor. Keep the letter, delivery records, pay stubs, time records, and messages about payment.
