Official bodies fetched for this page: Missouri Revisor RSMo § 290.230, DOLIR Prevailing Wage hub, DOLIR FAQs on overtime after ten / forty and OT/holiday on wage + fringe, DOLIR Prevailing Wage Law flowchart, and the Annual Wage Order look-up (AWO 33 in effect) — all HTTP 200.
RSMo § 290.230.1(2): For all work performed on a Sunday or a holiday, not less than twice the prevailing hourly rate of wages … or the public works contracting minimum wage … shall be paid … For purposes of this subdivision, "holiday" shall include each of the following: (a) January first; (b) The last Monday in May; (c) July fourth; (d) The first Monday in September; (e) November eleventh; (f) The fourth Thursday in November; and (g) December twenty-fifth; … If any holiday falls on a Sunday, the following Monday shall be considered a holiday.
RSMo § 290.230.1(3): For all overtime work performed, not less than one and one-half the prevailing hourly rate … "overtime work" shall include work that exceeds ten hours in one day and work in excess of forty hours in one calendar week.
DOLIR FAQ: overtime and holiday rates are based on the total of wages and fringe benefits combined — opposite of Oregon OAR 839-025-0050(2)(c), which excludes fringe from the OT base. Enter the combined prevailing rate. Subsection (4) requires a thirty-minute lunch each calendar day that is not time worked — unpaid lunch still comes off the punches; there is no separate lunch premium on this page. Projects with engineer’s estimate or accepted bid of $75,000 or less, maintenance work, volunteers, apprentices, and trade-specific General Wage Order holiday tables that differ from 290.230 are out of scope.
Weekday 10h 07:00–17:00 @ $20 → 10 regular = $200. OR PW without 4×10: 8 regular + 2 OT = $220. FLSA (under 40): 10 regular = $200.
Weekday 12h @ $20 → 10 regular + 2 OT = $260.
Saturday 8h @ $20 → 8 regular = $160. OR PW: 8 OT = $240.
Sunday 8h @ $20 → 8 DT = $320. OR PW: 8 OT = $240. FLSA: 8 regular = $160.
Legal holiday Monday 8h @ $20 → 8 DT = $320.
Five 10-hour weekdays @ $20 → 40 regular + 10 OT = $1,100.
Four 10-hour days Mon–Thu + Sunday 8h @ $20 → 40 regular + 8 DT = $1,120. OR PW with followed 4×10: 40 regular + 8 OT = $1,040.
Overnight weekday 20:00–08:00 lunch 30 @ $20 → 11.5h → 10 regular + 1.5 OT = $245.
