Labor Cost Variance After a Cafeteria Concept Change
A hospital cafeteria serving 1,400 meals per day converted from a traditional tray line to a scatter-style station concept six months ago. Patient satisfaction rose, but the food service director is now reviewing a labor variance: budgeted labor is 22% of revenue, actual is 27.5%. Revenue is flat at about $2.1 million annually. Overtime has risen from 3% to 9% of hours, and two part-time positions remain unfilled. The director also sees that the new stations require more skilled cooks, and the department is paying a shift differential to cover evening stations that previously closed at 6 p.m. The CFO wants a plan within 30 days.
1. Quantify the labor variance in dollars and break it into the most probable contributing components.

At $2.1 million revenue, the 5.5-point gap equals roughly $115,500 per year, or about $9,600 per month. Breaking it down:
- Overtime: moving from 3% to 9% of hours adds 6 percentage points of premium pay. If straight-time labor is roughly $460,000 (22% of revenue), the extra 6% of hours at time-and-a-half adds approximately $41,000 annually.
- Unfilled positions: two part-time roles at, say, $18/hour for 25 hours/week add about $46,800 in straight-time coverage if filled with overtime or agency staff, though the actual premium depends on how coverage is achieved.
- Shift differential and extended hours: evening stations open until 8 p.m. add differential pay and additional scheduled hours, plausibly $25,000-$35,000.
These components overlap, so the director should reconcile them against the payroll ledger rather than double-count. The point is to separate structural cost (the concept genuinely needs more hours) from waste (overtime from poor scheduling, unfilled roles).
2. Recommend a 30-day action plan and note which changes are structural versus temporary.

Structural (accept and rebudget): the scatter concept requires more skilled labor and longer service hours. The director should propose a revised labor standard (e.g., 25% of revenue) with justification, because pretending the old 22% is achievable will drive chronic overtime.
Temporary/waste (fix in 30 days):
- Fill the two part-time positions or convert them to one full-time role to reduce overtime premium.
- Rebuild the schedule around actual station demand; stagger start times so skilled cooks are not idle during slow periods.
- Cap overtime at 5% with a weekly approval process and track by station.
- Cross-train staff so one person can cover two stations during breaks, reducing relief overtime.
- Review the evening station menu for items that can be batch-produced earlier.
Report weekly to the CFO on overtime percentage, filled positions, and labor percentage. Be transparent that labor percentage will settle near 25%, not 22%, and explain the trade-off in satisfaction and revenue retention.
