TRS of Illinois

Post-Retirement Limitations

A retired Tier I member may work in a TRS-covered position for 100 days or 500 hours each school year and not lose benefits. A member's benefits are suspended if the limit is exceeded.

For post-retirement employment purposes, the Illinois Pension Code equates one full day with 5 hours. If an annuitant works only full days (five or more hours), each day is counted toward the 100-day limitation. If an annuitant works all partial days or a combination of full and partial days, the time worked would be counted toward the 500-hours limitation.

Each full day is counted as five hours even if more than five hours were worked that day. For partial days worked, the actual number of clock hours would be counted.


Monday Tuesday Wednesday Thursday Friday Total Hours Worked
0 hours worked 3 hours worked 0 hours worked 7 hours worked
(counted as 5 hours for full day)
0 hours worked 8 hours counted
toward 500-hour limitation

It is not permissible for an annuitant to combine partial days into full day equivalents to use the 100-day limit when the 500-hour limit applies. For example, an annuitant who works half days (3.5 hours) per day cannot work 180 days and count 90 days towards the post-retirement limits. Time worked must be counted against the 500-hour limit.

Only work that requires teacher certification (including summer school and substitute teaching) is subject to the days or hours post-retirement employment limitation. All time that a teacher or administrator is required to be present for duties requiring teacher certification is subject to the limitation. For teachers, this includes preparation periods and time before, between, and after classes. For administrators, this includes all time that is required to be spent on administrative duties, such as attendance at board meetings and contract negotiations.

Extra duties that do not require teacher certification (e.g., coaching, lunchroom supervision, chaperoning) are not subject to the 100 days or 500 hours post-retirement employment limitation.
