Rostering for the Lunch Rush: Peak Staffing for Quick Service Restaurants
30 October 2026 · The Rosterly team · 4 min read
Quick service restaurant peak staffing comes down to three things: know exactly when the rush starts and ends, roster by station (counter, drive-thru, grill, assembly) for each block, and stagger start times so people arrive as the queue builds. Cover breaks outside the peak, respect minimum shift lengths and review speed of service every week.
Quick service lives and dies by the lunch and dinner rush. Ninety minutes can make the day. Staff too few and the queue walks out; staff too many all day and labor cost eats the margin. Here's how to roster the peak precisely.
Step 1: Map the rush in 15-minute blocks
Hourly data is too coarse for quick service. Use your POS to see orders in 15-minute blocks for the last four weeks:
Time
Avg orders (weekday)
11:00–11:15
Avg orders (weekday): 8
11:30–11:45
Avg orders (weekday): 18
12:00–12:15
Avg orders (weekday): 32
12:15–12:30
Avg orders (weekday): 35
12:45–1:00
Avg orders (weekday): 26
1:30–1:45
Avg orders (weekday): 12
The real peak here is 11:45am to 1:15pm, shorter than "lunch" on the roster.
Step 2: Staff by station
Decide how many people each station needs at each order volume:
Orders per 15 min
Counter
Drive-thru
Grill
Assembly
Total
Under 10
Counter: 1
Drive-thru: 1
Grill: 1
Assembly: 1
Total: 4
10–20
Counter: 1
Drive-thru: 1
Grill: 2
Assembly: 1
Total: 5
20–30
Counter: 2
Drive-thru: 2
Grill: 2
Assembly: 2
Total: 8
Over 30
Counter: 2
Drive-thru: 2
Grill: 3
Assembly: 2
Total: 9
These are examples; use your own layout and speed targets.
Step 3: Stagger start times
Instead of everyone starting at 11am:
•
10:00am: openers and prep
•
11:15am: first peak staff
•
11:45am: second wave
•
1:15pm: first peak staff start finishing, depending on shift length
Staggered starts put people on as the queue builds, not an hour before.
Step 4: Keep breaks out of the peak
Nobody should be on break between 11:45 and 1:15. Schedule breaks for openers before the rush and for peak staff after. Check the break rules in your award, contract or local law.
Step 5: Mind minimum shift lengths
A 90-minute peak shift is often not possible. In Australia, the Fast Food Industry Award requires casuals to be engaged for at least 3 consecutive hours a day, and part-time employees to be rostered for at least 3 consecutive hours a shift. Build peak shifts of at least the minimum and use the extra time for prep or cleaning. Our post on casual minimum engagement covers other awards.
Step 6: Publish early
Quick service often has the strictest scheduling rules. In New York City, for example, covered fast food employers must give workers schedules 14 days in advance, with premium pay for changes inside that window, and can't schedule a clopening without written consent and a $100 premium. Even where no rule applies, early publishing reduces no-shows.
Roster the rush, not the whole day

Orders per labor hour in the peak and outside it.
3.
Labor cost percentage for the day.
If speed drops at 12:15 but labor is high at 2pm, move an hour from the afternoon to the peak. Our guide to how many staff you need per shift covers the method in more detail.
Common peak staffing mistakes
•
Rostering "lunch" as 11 to 3. The real peak is usually much shorter.
•
Breaks in the rush. One person on break at 12:30 is a whole station down.
•
No station plan. Extra people without a station stand around.
•
Ignoring drive-thru. It often peaks differently from the counter.
•
Same roster every weekday. Fridays and Mondays differ; roster each day.

This is a smaller store than the station table above assumes: it peaks just under 20 orders per 15 minutes and runs six people from 11:45am to 2pm (one more than the table suggests for that volume, as a buffer), with every peak shift at least three hours long. A store that regularly passes 30 orders per 15 minutes would add a third grill and a second assembly person to reach the nine the table suggests, staggering their starts in the same way.
Skills by station
Tag station skills, such as grill, drive-thru and register, so people are only rostered where they're trained. New starters should shadow at quieter times before working a peak station. Our skills-based scheduling guide explains how.
How Rosterly fits quick service
•
Peak templates: build station-based peak shifts as templates by location and copy them forward.
•
Skills: station skills are checked before anyone is assigned or claims an open shift.
•
Extra cover: auto-fill open peak shifts within a weekly hour limit you set.
•
Time and pay: staff clock in on their phones, unpaid breaks come off automatically, and approved hours export to CSV.
