chicago workers compensation process
chicago workers compensation process is the Illinois system administered by IWCC. Notify the employer no later than 45 days after the accident. The employer or its carrier pays medical care and temporary total disability at two-thirds (66 2/3%) of average weekly wage. The doctor's return-to-work note decides off-work versus light-duty, and TTD continues if the employer cannot accommodate.

Frequently Asked Questions
What is the first deadline in the chicago workers compensation process?
The IWCC handbook prints that the employee must notify the employer as soon as practicable, but no later than 45 days after the accident. Late notice can delay payment. Illinois statute text on ILGA also prints not later than 45 days after the accident. This page does not invent a shorter Chicago-only clock.
Who pays wage-loss benefits in Illinois?
The employer or its workers-comp carrier pays temporary total disability. The IWCC handbook prints that the TTD benefit is two-thirds (66 2/3%) of the employee's average weekly wage, subject to posted minimums and maximums. TTD is not paid for the first three lost workdays unless the employee misses 14 or more calendar days.
What role does the return-to-work note play in Chicago?
The treating doctor's work-status note is what tells the employer whether the worker is off work or released to do light-duty work. The IWCC handbook prints that TTD continues when the doctor releases the employee to light-duty work but the employer is unable to accommodate. A matching offer can end TTD and start a wage-difference analysis.
Why does this page omit an Illinois TTD dollar maximum?
The live IWCC benefits HTML fetched on 25 Aug 2026 is a JavaScript shell and does not print a weekly dollar cap in the response body. The older rates PDF on that site also does not print $2,045.63. This handbook therefore ships the printed two-thirds (66 2/3%) formula and omits an unsourced dollar maximum.
