Illinois OT follows federal FLSA: 1.5× past 40 hours/week.
Illinois has no state-level daily overtime rule, no consecutive-hour rule, and no spread-of-hours premium. All OT obligations flow through the federal FLSA: 1.5× the regular rate for hours over 40 in a fixed workweek. The complexity is in regular-rate calculation — non-discretionary bonuses, shift differentials, and commissions all factor in. Misclassification is the single largest source of FLSA back-wage exposure.
Federal Weekly Overtime + Regular Rate
Tracks running weekly hours toward the 40-hour FLSA threshold. Calculates the regular rate including non-discretionary bonuses, shift differentials, and commissions. Pays 1.5× automatically.
What those rules do as a workweek crosses 40 hours.
The hero card configuration: Avoid at 36 hours scheduled, Critical on payroll close, Flag on the timesheet.
When a worker's scheduled hours plus a pending shift would push past 36 hours, the manager sees a yellow indicator: "Adding this trends past weekly OT." Save proceeds, exposure logged.
On payroll close, any worker whose week exceeded 40 hours surfaces with a Critical indicator and the calculated premium. Close requires explicit confirmation.
Hours past 40 in a workweek auto-tag as Weekly OT. Payroll sees the tag and applies 1.5× the regular rate automatically.

Forty hours in a fixed seven-day workweek — federal only.
Illinois adopts the federal FLSA framework. The simplicity at the threshold (only weekly OT) hides complexity in regular-rate calculation.
Workweek is fixed and recurring
A workweek is any fixed, recurring 168-hour period (7 × 24). The employer designates the start day and time but cannot shift it to evade OT. Different workweeks per worker are allowed (common in healthcare staffing) but each must remain consistent.
Regular rate isn't always the hourly rate
The 'regular rate' includes all remuneration except specific statutory exclusions: non-discretionary bonuses, shift differentials, commissions, and certain incentive pay all factor in. Calculating the regular rate wrong is the #1 source of FLSA OT lawsuits.
Teambridge tracks the workweek and calculates the true regular rate.
The hard part of FLSA OT in Illinois isn't the 40-hour threshold — it's getting the regular rate right when a worker has a base rate plus differentials, bonuses, or commissions.
36-hour line shows up early.
When a manager schedules a shift that would push a worker past 36 weekly hours, an Avoid indicator surfaces. Manager can proceed or redistribute.
Hours follow the worker.
If a worker has shifts at multiple of your locations, Teambridge aggregates the hours under one workweek total. The OT calculation considers everywhere the worker clocks.
All earnings rolled in.
When OT is owed, Teambridge calculates the regular rate including base wages, shift differentials, non-discretionary bonuses, and commissions earned in the workweek.
Pay-period boundaries don't matter.
When a workweek crosses into a new pay period (common with semi-monthly pay schedules), Teambridge keeps the OT calculation tied to the workweek, not the pay period.
