Warehouse Labor Shortages: A Guide to Building a More Flexible, Resilient Operation

Warehouse labor shortages can create problems far beyond an open position.

When a distribution center cannot consistently match labor capacity to workload, the effects can spread throughout the operation: overtime increases, trailers wait longer, receiving falls behind, orders become harder to process on schedule, supervisors spend more time solving staffing problems, and labor cost becomes increasingly difficult to control.

For grocery retailers, foodservice distributors, 3PLs, retailers, manufacturers and other high-volume distribution operations, the challenge is often not simply finding more workers.

It is building a labor model that can expand and contract as operational demand changes.

That is where flexible warehouse labor can provide a different approach.

Rather than maintaining enough permanent headcount to cover every possible peak—or relying on temporary workers whenever the operation falls behind—a flexible labor strategy creates additional capacity that can be deployed where and when the operation needs it.

The objective is not simply to fill positions.

It is to keep the operation moving.

What Causes Warehouse Labor Shortages?

Warehouse labor shortages occur when the workforce available to an operation is insufficient to meet its labor requirements.

But the underlying cause is rarely just a lack of applicants.

Warehouse labor requirements can change considerably based on:

Seasonal demand
Daily and weekly volume fluctuations
Employee turnover
Absenteeism
New customer growth
Promotional activity
Inbound freight variability
Second- and third-shift requirements
Geographic labor availability
New facility startups
Product and SKU expansion
Unexpected backlogs
Changes in customer demand

The broader labor market can compound these operational challenges.

For example, U.S. Bureau of Labor Statistics data reported approximately 392,000 job openings across transportation, warehousing and utilities in June 2026, up from approximately 295,000 in May. The data does not measure warehouse vacancies specifically, but it illustrates the continuing competition for workers across the broader transportation and warehousing labor market.

For individual distribution centers, however, national employment statistics are only part of the story.

A warehouse can face a significant labor shortage even when the national labor market appears relatively balanced.

The question that matters operationally is much more specific:

Do you consistently have enough productive labor, on the right shifts and in the right functions, to handle the volume moving through your facility?

If the answer changes depending on the week, season or volume level, the operation may have a labor-capacity problem rather than simply a hiring problem.

Why Hiring More Employees Doesn’t Always Solve Warehouse Labor Shortages

The traditional solution to a warehouse labor shortage is straightforward:

Hire more people.

Sometimes that is exactly the right answer.

But maintaining a larger internal workforce also introduces additional costs and operating responsibilities.

Those can include:

Recruiting
Screening
Onboarding
Training
Scheduling
Supervision
Payroll administration
Benefits
Workers’ compensation
Employee relations
Performance management
Turnover replacement
Overtime management

There is also a more fundamental challenge.

Warehouse volume is rarely perfectly consistent.

If a distribution center hires enough permanent employees to comfortably handle its highest-volume periods, it may carry excess labor capacity during slower periods.

If it staffs around average demand, the opposite occurs.

When volume increases, the facility can become understaffed.

That creates the classic warehouse labor dilemma:

Staff for the average and struggle during peaks, or staff for the peak and carry excess cost when demand falls.

A flexible labor model creates a third option.

What Is Flexible Warehouse Labor?

Flexible warehouse labor is a workforce model that allows a distribution operation to adjust labor capacity as operational demand changes.

Instead of depending exclusively on a fixed internal workforce, an organization can use additional labor resources to support defined warehouse functions, shifts, facilities or periods of increased demand.

Flexible labor may support activities such as:

Unloading
Receiving
Put-away
Replenishment
Selection
Order fulfillment
Cross-docking
Returns
Inventory handling
Shipping
Other labor-intensive warehouse functions

The goal is not simply to increase headcount.

The goal is to create variable operational capacity.

That distinction matters.

Flexible Warehouse Labor vs. Temporary Staffing

Flexible warehouse labor is often confused with temporary staffing.

They are not necessarily the same thing.

A temporary staffing company primarily supplies workers.

A managed warehouse labor provider can assume responsibility for an operating function and the performance of the workforce assigned to it.

Traditional Temporary Staffing	Managed Flexible Warehouse Labor
Supplies individual workers	Provides an operating labor solution
Customer manages workers	Provider can supply onsite management
Typically hour-based	Can be aligned with productivity or production
Customer handles daily performance	Provider manages workforce performance
Headcount is the primary deliverable	Operational output is the primary objective
Customer absorbs much of the supervision burden	Management responsibility can shift to the provider
Used primarily to fill labor gaps	Used to create scalable operating capacity

That is an important distinction for warehouse operators.

A facility experiencing recurring operational pressure may not need another source of hourly workers.

It may need a partner that can take responsibility for producing results within a defined portion of the operation.

When Does Flexible Warehouse Labor Make Sense?

Flexible warehouse labor can be valuable whenever the amount of work moving through a facility changes faster than the internal workforce can efficiently adjust.

Common situations include:

Seasonal Volume

Grocery, retail and consumer distribution networks can experience significant volume increases around holidays, promotions and seasonal buying patterns.

Building permanent headcount around temporary demand can create unnecessary labor expense after the peak passes.

Flexible capacity allows labor resources to better follow the workload.

Second- and Third-Shift Coverage

Some facilities can recruit adequately for first shift but struggle to maintain reliable staffing on nights, weekends or other less-desirable schedules.

That can create operational bottlenecks even when total facility headcount appears adequate.

Unexpected Volume Increases

New customers, promotions, supply-chain disruptions or changing order patterns can create workload faster than recruiting can produce new employees.

Flexible warehouse labor provides another source of operational capacity.

Persistent Overtime

Occasional overtime is a normal part of many warehouse operations.

Persistent overtime may indicate that an operation’s baseline labor capacity no longer matches its workload.

When overtime becomes structural rather than exceptional, it is worth evaluating whether additional flexible capacity would be more efficient.

New Facility Startups

Starting a warehouse or distribution center requires recruiting and training a large workforce while simultaneously establishing processes and meeting customer expectations.

A managed labor partner can help provide operating capacity while the permanent organization develops.

Backlogs and Recovery Situations

Facilities can fall behind because of weather, labor disruptions, unexpected inbound volume, equipment problems or other events.

Additional labor capacity can help restore the operation without permanently expanding internal headcount.

Rapid Growth

Customer growth is good.

But when volume expands faster than workforce availability, growth itself can create service problems.

Flexible warehouse labor can help bridge the difference between commercial growth and internal labor capacity.

How Do You Know When Your Internal Labor Model Has Reached Its Scaling Limit?

One of the most important questions for an operations leader is not:

“Can we hire more people?”

It is:

“Can our current labor model continue scaling efficiently?”

Warning signs can include:

Overtime Has Become Normal

If overtime is consistently required simply to complete normal weekly volume, the operation may no longer have enough baseline capacity.

Supervisors Spend Too Much Time Solving Staffing Problems

Operational leadership should be focused on throughput, safety, inventory accuracy, process improvement and customer performance.

When supervisors spend significant portions of their day recruiting, filling call-outs and rearranging schedules, labor administration begins competing with operations management.

Peak Periods Consistently Create Backlogs

A facility that performs well at average volume but repeatedly struggles during predictable peaks may need variable capacity rather than additional fixed headcount.

Labor Cost Is Growing Faster Than Throughput

Higher labor expense does not necessarily produce higher productivity.

An operation should evaluate not just cost per hour, but the relationship between labor expense and output.

Temporary Labor Has Become Permanent

Temporary staffing can be extremely useful for short-term needs.

But if large numbers of temporary employees have become a permanent component of the operation, it may be worth determining whether a managed labor model would create greater accountability.

Turnover Prevents the Workforce From Stabilizing

Constant recruiting can create a cycle in which new employees are continually replacing departing employees rather than increasing productive capacity.

Less-Desirable Shifts Remain Chronically Understaffed

A warehouse may have adequate total headcount while still experiencing major capacity problems on specific shifts.

The operation must be staffed where and when the work occurs.

What Are the Hidden Costs of Internal Warehouse Labor Management?

The hourly wage of an employee is only one component of warehouse labor cost.

Internal labor management can also involve:

Recruiting expense
Human resources administration
Training time
Supervisor time
Payroll taxes
Workers’ compensation
Benefits
Overtime premiums
Turnover
Absenteeism
Idle labor
Productivity variation
Safety administration
Employee relations
Scheduling complexity

For that reason, comparing an outsourced or managed labor rate directly against an employee’s hourly wage can create an incomplete picture.

The more useful comparison is often:

What does it cost the operation to produce the required amount of work?

That shifts the conversation from cost per labor hour to measures such as:

Cost per case
Cost per pallet
Cost per load
Cost per unit
Throughput per labor hour
Dock-to-stock time
Trailer dwell
Overtime
Service-level performance

That is where warehouse labor becomes an operational strategy rather than simply a staffing expense.

How Can Flexible Labor Improve Warehouse Operations?

Flexible labor creates value when labor capacity becomes more closely aligned with workload.

1. Greater Scalability

Operations can increase labor capacity when volume rises without necessarily building permanent headcount around peak demand.

2. Reduced Pressure on Internal Recruiting

The internal organization does not have to independently source every worker required to support changing operational needs.

3. Better Protection Against Volume Volatility

Promotions, seasonal increases, unexpected inbound volume and customer growth become easier to absorb when additional capacity is available.

4. Less Reliance on Overtime

Flexible resources can provide another way to increase capacity before an operation becomes dependent on excessive overtime.

5. Increased Management Focus

When a managed labor partner assumes responsibility for workforce supervision and performance, internal leaders can concentrate more heavily on the operation itself.

6. Greater Labor-Cost Visibility

When performance is measured against production, companies can better understand the relationship between labor spending and actual output.

7. Improved Operational Resilience

A resilient distribution center is not one that never experiences disruption.

It is one that has the capacity to respond when disruption occurs.

Flexible labor provides an additional lever management can use when requirements change.

How Much of a Warehouse Workforce Should Be Flexible?

There is no universal percentage.

The right combination depends on the facility.

An effective labor strategy can begin by separating demand into two categories:

Base Demand

The relatively predictable volume that exists throughout the year.

This portion of the operation may be well suited for a stable internal workforce.

Variable Demand

The difference between baseline demand and the labor required during peaks, seasonal changes, promotional periods, unusual inbound volume or other fluctuations.

This is where flexible capacity can become particularly valuable.

A warehouse does not necessarily need to choose between an entirely internal workforce and an entirely outsourced workforce.

A hybrid model can allow an organization to retain its core workforce while creating additional capacity around it.

Can You Outsource Warehouse Labor Without Outsourcing the Entire Operation?

Yes.

Warehouse labor outsourcing does not have to mean turning over the entire distribution center to a third-party logistics provider.

A company can retain control of:

Inventory
Warehouse systems
Customer relationships
Procurement
Transportation strategy
Facility management
Operating standards
Quality standards
Overall supply-chain strategy

while outsourcing specific labor-intensive functions.

For example, a company might retain management of its distribution center while using a managed labor partner for unloading, receiving, put-away, replenishment or other defined processes.

This approach allows the customer to retain control of its operation while transferring responsibility for selected labor functions to a specialized provider.

Put simply:

Do what you do best. Outsource the rest.

What Should You Look for in Warehouse Staffing Services?

Companies researching warehouse staffing services should look beyond the number of workers a provider says it can supply.

The more important question is:

Who is responsible for the result?

Consider evaluating potential providers based on:

Onsite Management

Will the provider supervise its own workforce, or will your supervisors be responsible for managing those employees?

Productivity Measurement

How will performance be measured?

Look for providers capable of connecting labor activity to meaningful operational output.

Scalability

Can the provider expand and contract with your business?

Shift Coverage

Can the provider support the specific shifts where your operation experiences shortages?

Safety

How are workers trained, managed and held accountable for safe operating practices?

Reporting

Will management receive visibility into productivity, labor utilization and performance?

Recruiting Capability

Can the provider consistently maintain workforce availability in your market?

Operational Experience

Does the provider understand warehouse operations, or does it primarily understand staffing?

Accountability

If performance falls short, who is responsible for correcting it?

The difference between a staffing vendor and an operational partner often becomes clear in the answer to that final question.

Internal Warehouse Labor vs. Managed Flexible Labor

The appropriate workforce model depends on the operation, but comparing the two can reveal where additional flexibility may create value.

Internal Labor	Managed Flexible Labor
Fixed workforce capacity	Capacity can scale with demand
Recruiting managed internally	Recruiting responsibility shifts to provider
Internal supervision	Provider can supply onsite management
Turnover managed internally	Provider manages workforce continuity
Peaks can create overtime	Additional capacity can support peaks
Slow periods can create excess capacity	Workforce can better follow workload
Labor commonly measured by hours	Performance can be tied to production
HR burden remains internal	Defined labor administration transfers to provider

For some facilities, the best answer is not one model or the other.

It is a combination.

A strong permanent workforce can provide stability while managed flexible labor creates the additional capacity required to deal with operational variability.

How Does Flexible Warehouse Labor Affect Cost Per Case?

The lowest hourly labor rate does not necessarily create the lowest operating cost.

Consider two labor models.

One has a lower hourly wage but experiences:

High overtime
Low productivity
Frequent turnover
Idle time
Significant supervision requirements
Inconsistent throughput

Another has a higher apparent labor rate but produces more units per hour with less internal management.

The second operation may ultimately have the lower cost per unit of production.

That is why sophisticated warehouse labor analysis should evaluate metrics such as:

Total labor cost ÷ total production = labor cost per unit

Depending on the operation, the unit might be:

Cases
Pallets
Units
Orders
Loads
Containers

When warehouse operators begin managing labor around productivity instead of headcount alone, the economics can look very different.

How Can Warehouses Reduce Overtime?

Reducing overtime begins with understanding why it exists.

If overtime is caused by an occasional unexpected event, adding permanent headcount may not make sense.

If it happens every week, however, the operation may have a structural capacity problem.

Warehouse leaders should evaluate:

Normal weekly workload
Available productive labor hours
Productivity by function
Volume by day and shift
Absenteeism
Turnover
Peak-period requirements
Overtime hours
Labor cost per unit
Available flexible capacity

Flexible labor can then be deployed specifically where the capacity gap occurs rather than simply adding headcount throughout the facility.

How Should Distribution Centers Plan Warehouse Labor for the Next 12–24 Months?

A useful workforce plan should answer six questions.

1. What Is Our Baseline Volume?

Determine the amount of work the facility processes during normal operating conditions.

2. What Does Peak Volume Look Like?

Identify predictable seasonal, weekly and promotional increases.

3. How Much Productive Labor Is Required?

Translate workload into actual labor requirements by process and shift.

4. Where Are the Gaps?

Identify the difference between available labor capacity and required labor capacity.

5. What Does That Gap Cost Us Today?

Include more than wages.

Evaluate:

Overtime
Temporary labor
Turnover
Recruiting
Supervisor time
Backlogs
Service failures
Detention
Lost productivity

6. Which Capacity Should Be Permanent and Which Should Be Flexible?

Then determine what portion of the workforce should remain internal and where variable capacity could reduce operating risk.

That produces a labor strategy based on operational requirements rather than simply headcount.

Frequently Asked Questions About Warehouse Labor Shortages

What causes warehouse labor shortages?

Warehouse labor shortages can result from limited workforce availability, turnover, absenteeism, seasonal volume, shift requirements, rapid growth, geographic labor conditions and fluctuations in operational demand. A shortage occurs operationally when available productive labor cannot consistently meet the workload required by the facility.

How can warehouses solve labor shortages?

Potential solutions include improving retention and recruiting, increasing productivity, adjusting schedules, using automation, reducing unnecessary processes and creating flexible labor capacity. The appropriate solution depends on whether the shortage is caused by a permanent workforce deficit or changing demand.

What is flexible warehouse labor?

Flexible warehouse labor is a workforce model that allows a distribution center to increase or decrease labor capacity based on operational requirements instead of depending entirely on fixed internal headcount.

What is the difference between warehouse staffing and managed warehouse labor?

Warehouse staffing primarily supplies workers. Managed warehouse labor can include recruiting, supervision, performance management and accountability for specific warehouse functions or production outcomes.

How do warehouses scale labor during peak periods?

Warehouses can use overtime, seasonal employees, temporary workers, cross-training, automation or managed flexible labor. The most appropriate solution depends on the duration, predictability and size of the volume increase.

Can warehouse labor be outsourced without outsourcing the entire warehouse?

Yes. Companies can outsource individual warehouse functions such as unloading, receiving, put-away, replenishment, selection or other labor-intensive activities while retaining control over the facility, inventory, systems and overall operation.

How can warehouse operations reduce overtime?

Warehouses can reduce overtime by improving productivity, balancing staffing by shift, planning around predictable volume, reducing turnover and adding flexible capacity when workload exceeds the productive hours available from the core workforce.

When should a company consider outsourcing warehouse labor?

Outsourcing may be worth evaluating when a facility experiences persistent overtime, recurring staffing shortages, high turnover, difficulty scaling during peaks, excessive management time devoted to labor administration or inconsistent productivity.

What should companies look for in warehouse staffing services?

Companies should evaluate management responsibility, workforce availability, productivity measurement, safety, training, reporting, scalability, operational expertise and accountability—not simply hourly labor rates.

How does flexible labor improve warehouse resilience?

Flexible labor gives warehouse operators another source of capacity when volume, attendance or operating conditions change. This can help organizations maintain throughput without maintaining peak-level permanent headcount throughout the year.

From Warehouse Staffing to Warehouse Performance

Warehouse labor will always involve people.

But the most effective labor strategies are not built around headcount alone.

They are built around the work that must get done.

For operations experiencing persistent warehouse labor shortages, rising overtime, turnover, inconsistent shift coverage or difficulty scaling with volume, the better question may not be:

“Where can we find more workers?”

It may be:

“How should we structure our labor model so our operation can scale?”

That change in perspective can transform warehouse labor from a recurring staffing problem into a strategic operating decision.
