Seasonal warehouse staffing: your month-by-month Q4 playbook for Utah

It is the third week of August. The dock is quiet, your crew is caught up, and the only thing on your calendar is a budget meeting nobody is looking forward to.

This is the week it starts.

Not the volume. That does not show up until the second week of November, when the carrier pickup window slides an hour later every night and the order board goes from busy to something else. But seasonal warehouse staffing does not run on the volume's schedule. The crew that works that November is being decided right now.

Maybe last year you were short 14 people the week before Thanksgiving, covered it with mandatory overtime, and watched your two best leads spend December looking at job boards on their lunch break.

Here is what nobody tells operations managers: this is not a recruiting problem. It is a scheduling problem. The fill rate you get in November is not set by how hard your agency works in November. It is set by what you locked in during August and September, while the labor pool was still yours to claim.

So here is the calendar. Three phases, five months, and the decisions that belong in each one.

Why peak season staffing is a calendar problem

Start with the market you are hiring into.

Utah's unemployment rate sat at 3.6% in June 2026, and transportation and warehousing grew 2.0% over the prior 12 months, faster than the broader trade, transportation, and utilities category it sits inside, according to the Utah Department of Workforce Services. The buildings along I-15 and I-80 are adding capacity, and the pool of people available to staff them is not growing to match.

Nationally, BLS data for June 2026 shows 3.2 million quits in a single month, with openings in transportation, warehousing, and utilities up by 97,000. Meanwhile the seasonal pool keeps thinning. Challenger, Gray & Christmas counted 303,700 seasonal positions added in transportation and warehousing in Q4 2024, the lowest since 2019, and projected a further decline. That does not mean less competition for good workers. It means the employers still hiring are moving earlier.

So the external problem is simple. You need 30 or 60 or 120 extra people for eight weeks, and the ones who can do the work are largely spoken for by mid-October. The internal problem is that you know what it feels like to walk the floor at 6 AM, eight people short, with the truck coming anyway.

And here is the part that should bother you. Your core crew absorbs the shortfall. They work the doubles. They train the temps nobody had time to onboard. A plan that runs on their backs is a loan against your best people, and the interest comes due in January.

Your month-by-month seasonal staffing playbook

August and September: forecast the headcount, lock the partner

You will not get the forecast exactly right. Forecast anyway, because a number you can revise beats a number you do not have.

1. Build headcount by week, not by season. "We need 40 temps for Q4" is not something a partner can execute. "We need 12 the week of October 12, 28 by November 2, and 40 through December 19" is.
2. Set the wage band before the headcount. Nobody can recruit against a rate you have not approved, and "we are still finalizing that" in September is the most common reason a ramp starts late.
3. Define screening now. Background check depth, E-Verify, drug screening, equipment certification. Every requirement extends the clock.
4. Sign the partnership in September. This has to be a date, not an intention. A partner who knows your building and your rates by the end of September can put people in front of you in October. One who hears from you in November is recruiting for whoever is left.

October and November: onboard in waves, hold what you hired

October is where good plans die, because the operational load and the hiring load land in the same weeks.

1. Onboard in waves of eight to 12. A wave that size can be safety-oriented and floor-trained by one lead in a single shift. Thirty people on a Monday get a badge, a vest, and a vague gesture toward the pick line.
2. Write the training down before peak. One page per role. Not a manual. What the job is, what good looks like, what to do when the scanner errors out, and who to ask.
3. Pair every temp with a named person. Not "the team." A name. Retention in the first 10 days is almost entirely a function of whether a new worker knows who to ask.
4. Protect your core crew's schedule. Decide in October how much overtime you will ask of your permanent team, and hold that line. The point of seasonal help is that your leads get to go home.

Worth saying plainly: the people on your dock in October are somebody's neighbor who took a job that starts at 5 AM because it pays and they need it. Treat onboarding like it matters to them and it shows up in your fill rate. That is why we offer day-one healthcare benefits to temporary workers.

December: convert your best seasonal workers instead of losing them

By the first week of December you know who your keepers are. There may be up to 12 of them, and most warehouses let all of them walk on December 23.

1. Make the list by December 5. Names, roles, and a yes or no on whether you would keep them if the headcount existed.
2. Have the conversation before the last week. By December 20 your best seasonal workers are already interviewing elsewhere.
3. Know your conversion mechanics. At LG Resources, temporary workers become eligible for direct conversion after 480 hours, which is 12 weeks of full-time work. A 10-week seasonal run lands near 400 hours, so check where each person sits before you make an offer.
4. Do the exit conversation for everyone else. Five minutes, specific about whether you would take them back next August. Someone who leaves on good terms is a pre-screened candidate for next year.

SHRM puts average cost per hire at nearly $4,700 for a stranger. For someone who has run your equipment for 10 weeks, you already absorbed that cost. That is why temp-to-hire works so well for seasonal peaks.

What a two-week delay costs your fill rate

A delay does not cost you two weeks. It costs you the difference between recruiting in a normal market and recruiting in a picked-over one.

Say you need 40 seasonal workers by November 2. Start that ramp in September and a well-matched partner can typically fill it. Start it on October 20 and you are pulling from what is left after every other distribution center in the valley has hired. Assume that leaves you 25% short, or 10 unfilled positions across an eight-week peak.

• The overtime premium. Ten positions at 40 hours is 400 hours a week that still has to happen. You were always going to pay straight time for that work, so the delay costs the premium, not the whole wage. Cover half at a $20 base and the extra $10 an hour runs $2,000 a week, or about $16,000 across the peak.
• Turnover you caused. Warehouse turnover already runs near 49% a year, according to BLS figures compiled by KPI Solutions, whose model puts the cost of replacing one warehouse worker at about $18,600. Lose two burned-out leads in January and you are out roughly $37,000.
• The orders you did not ship. Deloitte's most recent holiday forecast put ecommerce growth at 7% to 9% for the November-to-January season. A missed ship window in your peak week is a customer conversation in January.

North of $53,000 in traceable cost, from two weeks of hesitation in September.

Frequently Asked Questions

When should you start hiring seasonal warehouse workers?

Start in August, and have your staffing partnership signed by the end of September. The practical rule is 10 to 12 weeks before your first heavy week. Starting later does not simply compress the timeline. It changes the candidate pool you are recruiting from, because the strongest seasonal workers commit early.

How long does it take to fill a warehouse position?

For a single position with an approved rate and defined screening requirements, a staffing agency with an active local pool can often place someone within a day or two. A full seasonal ramp of 30 or more workers realistically needs six to eight weeks, because it depends on screening throughput, onboarding capacity, and how many other employers are recruiting the same people at the same time.

How many seasonal workers do I actually need?

Build the number from weekly outbound volume rather than a seasonal total. Take last year's units shipped by week, divide by your actual units-per-labor-hour rate, subtract the capacity your permanent crew can cover at a schedule you are willing to defend, and the remainder is your seasonal headcount by week. Add a 10% buffer for attrition during the ramp.

Can you hire a temporary worker permanently?

Yes, and for seasonal workers who have already proven themselves it is usually the least risky hire available to you. Conversion terms vary by agency, so confirm the specifics in your service agreement before peak begins. At LG Resources, temporary workers become eligible for direct conversion after 480 hours on assignment, which is 12 weeks of full-time work. A 10-week seasonal assignment lands near 400 hours, so a worker you want to keep may need a short extension to reach the threshold.

What is a good fill rate for seasonal warehouse staffing?

A well-planned seasonal ramp should land at 90% or better of requested headcount by your target start date. Below 80% and you are running the peak on overtime, which shifts the cost from your staffing line to your payroll line and onto your permanent crew. Ask a prospective partner for their fill rate on comparable ramps last Q4, in writing.

Do temporary warehouse workers get benefits?

It depends entirely on the agency, and the difference is larger than most employers realize. Many staffing firms offer temporary workers no benefits at all or impose a 30 to 90 day waiting period. LG Resources provides benefits from day one, including a carrier-based limited benefit medical plan with 24-hour telemedicine at no copay and no deductible, at $20 a month or less per employee. Beyond the ethical case, workers with healthcare access take fewer unplanned absences during the weeks you can least afford them.

Summing Up

Peak season does not reward the operations manager who works hardest in November. It rewards the one who made four phone calls in August.

Picture the second Monday in November. You walk the floor at 6 AM and the crew is complete. Not "mostly there." Complete. Your two leads are on their normal shifts, because you decided that back in October.

The alternative is the November you already know. Short crew, mandatory overtime, and a January conversation about why the numbers missed. You have run that season. You do not have to run it again.
