Staffing for Seasonal Peaks: Temporary Help, Overtime and Cross-Training
Most small service businesses cover their busy season by asking the same people to work longer, and the research on hours and output, along with the overtime math, suggests a planned mix of seasonal help and cross-training usually costs less and holds quality better.
At a glance
- Seasonal staffing is the plan for covering the extra hours a busy season brings, using some mix of overtime, temporary or seasonal hires and staff cross-trained to cover more than one role.
- Peaks can be steep: payroll employment in tax preparation services ran from about 142,200 in February 2022 to about 62,300 that August, according to the Bureau of Labor Statistics.
- A study of output and working hours found that output rose in step with hours only up to about 49 hours a week, and that output at 70 hours differed little from output at 56.
- For an illustrative business needing 60 extra hours a week for ten weeks, covering it all with overtime costs about $21,600, against about $17,280 for seasonal hires including training.
- Federal rules set the floor: overtime at time and a half after 40 hours in a workweek, and hour limits for workers aged 14 and 15.
Part 1 | Longer weeks are the default, and they cost more than they seem
The first instinct in a busy season is to keep it in the family, and the owner's inner voice says My people know the work; they can handle a few long weeks. For a short spike that can be right. Over a season of eight to twelve weeks, though, overtime raises the cost of each extra hour by half and, past a certain point, buys less work per hour.
The clearest evidence on that second point comes from a study of historical output records for munition workers, published as an IZA discussion paper, which found that below 49 hours a week, output moved in proportion to hours, while above that threshold output rose at a decreasing rate, peaking at about 63 hours; output at 70 hours differed little from output at 56. Modern service work is different from a munitions factory, but the pattern of diminishing returns is a reason to watch for the small mistakes that lead to redos and callbacks when a stylist is on a sixth straight 10-hour day or a technician is on a twelfth call of the week.
Federal law sets the cost side. Under the Fair Labor Standards Act, covered non-exempt employees must be paid at least time and a half their regular rate for hours over 40 in a workweek, the workweek is a fixed and recurring 168-hour period, and hours can't be averaged across two weeks, according to the Department of Labor's Fact Sheet #23. The regular rate includes all pay for employment except payments the law specifically excludes, so commissions and many bonuses count and overtime for a commissioned stylist or a technician on spiffs is usually more than 1.5 times the hourly base. General information, not legal/tax/financial advice; talk to a licensed professional about your situation.
Part 2 | Three ways to cover the peak, priced side by side
Most businesses end up using all three tools, and the useful question is the mix. Overtime needs no hiring or training, but costs half again per hour and runs into the hours-and-output limit if it stretches over a season. Seasonal or temporary hires cost the regular rate plus payroll taxes and training time, or an agency's markup if you hire through one. Cross-training moves existing staff into the work that peaks, such as a front-desk employee who can prep rooms or a service manager who can run a second truck, so the extra hours land where the demand is.
| Extra labor hours needed per week (Assumption) | 60 |
|---|---|
| Weeks in the peak (Assumption) | 10 |
| Regular hourly rate (Assumption) | $24 |
| Overtime rate (Calculated ($24 × 1.5)) | $36 |
| Cost if covered entirely by overtime (Calculated (60 × $36 × 10)) | $21,600 |
| Payroll taxes and costs on a seasonal hire (Assumption) | 10% |
| Seasonal hire cost per hour (Calculated ($24 × 1.10)) | $26.40 |
| Training: 40 hours for new hires plus 20 hours of trainer time (Calculated (60 × $24)) | $1,440 |
| Cost if covered entirely by seasonal hires (Calculated (60 × $26.40 × 10 + $1,440)) | $17,280 |
| Cost of a mix: 40 hours from seasonal hires, 20 hours of overtime (Calculated ($10,560 + $1,440 + $7,200)) | $19,200 |
Illustrative example; replace every assumption with your own numbers.
The mix can still be the better choice even though it costs more on paper than all seasonal hires. Spread across three employees, 20 hours of overtime adds about 7 hours each and keeps weekly hours under 47, inside the range where the research found output still tracks hours, while one seasonal hire is easier to find and train than two. All-overtime coverage of 60 hours, spread the same way, would put each of those three employees at 60 hours a week for ten weeks.
Part 3 | Building the seasonal team before the season starts
The businesses that handle peaks calmly start recruiting six to eight weeks ahead, because seasonal hiring competes with every other seasonal employer in town. A short list of habits keeps the plan on track:
- Write the peak schedule first. Use last year's bookings by week to set how many extra hours each week needs, rather than hiring a headcount.
- Bring back last year's seasonal staff. A returning worker needs a refresher, not a full training, so keep in touch during the off-season.
- Cross-train in the slow months. Pair each employee with a second role for a few hours a week in the quiet season, using a written checklist, so they can cover in the peak.
- Cap the overtime. Set a weekly limit per person, such as 48 hours, and track it with the schedule rather than discovering it on the payroll report.
- Check the rules for teen hires. Under federal law, workers aged 14 and 15 in nonagricultural jobs may work up to 3 hours on a school day, 18 hours in a school week, 8 hours on a non-school day and 40 hours in a non-school week, between 7 a.m. and 7 p.m., extended to 9 p.m. from June 1 through Labor Day, according to the Department of Labor's Fact Sheet #43; states may set stricter limits.
How you compare
- Your peak-to-low ratio: divide your busiest month's labor hours by your quietest month's. Tax preparation runs at about 2.3 by the BLS figures; a ratio above 1.3 calls for a written seasonal plan.
- Your overtime share: add up overtime hours in last year's peak and divide by all hours worked. If overtime covered most of the peak, compare its cost with Exhibit 2.
- Your own baseline: note last season's redos, callbacks or complaints by week, and check whether they rose in the weeks with the longest hours.
Questions to ask this week
How many extra hours did our last peak actually need? Payroll and booking records for each week of the peak give the answer.
Who on the team could cover a second role with a few hours of practice? That list is your cross-training plan.
Which of last year's seasonal workers would we hire again? A short note now keeps them in mind for next season.
What is our weekly hours cap? Write one down before the season, not during it.
Before the next peak, pull last year's hours by week, price the three options with the table above and decide the mix, so the hiring starts six to eight weeks ahead.
About this research: This article draws on Bureau of Labor Statistics monthly employment data published in The Economics Daily, an IZA discussion paper on the productivity of working hours based on historical records for munition workers, and Department of Labor fact sheets on overtime and child labor. The worked example is illustrative. The hours-and-output study is historical and is used here for its pattern, not as a precise threshold for service work.
