5 mistakes that kill staffing during peak season (and how to avoid them)

September 15, 2025

Peak season is make-or-break. Whether you’re running logistics, retail, hospitality, or any high-volume operation, what happens in the next 8–10 weeks will ripple into your margins, customer satisfaction, and team burnout for months. 

We’ve worked with dozens of high-volume employers to prep for seasonal demand. And every year, we see the same five mistakes derail even the most experienced teams. 

Here’s what to watch for—and what you can do differently this time around. 

1. Starting recruitment too late...or too early

The mistake: Waiting until demand is already surging before onboarding seasonal workers. 

By the time you “feel” the spike, it’s already too late. Candidate pools have dried up, lead times stretch, and managers start taking whoever shows up—qualified or not. 
 
But starting too early has its own risks: workers don’t want to sit around for weeks waiting to be scheduled, and early hires often disengage or take other roles before your peak even begins. 

The fix: Build your talent pool early and make onboarding fast.

JoinedUp lets you bulk-import workers, match skills to shifts, and get compliant in one go—so you’re not scrambling when the heat hits.

 

2. Ignoring worker availability & preferences

The mistake: Assuming workers will flex.

In reality, seasonal staff often juggle multiple gigs, unpredictable commutes, or childcare constraints. If you’re assigning shifts without seeing true availability, you’re inviting no-shows, burnout, and double-bookings.

The fix: Respect workers’ real lives.

With JoinedUp’s mobile-first availability tools, workers can set preferences, confirm shifts, and self-serve—dramatically reducing ghosting and comms overhead. 

 

3. Overlooking compliance in the rush

The mistake: Cutting corners when things get busy. 

It’s tempting to skip right-to-work checks, training validations, or health & safety protocols when demand peaks. But one audit or incident can leave you exposed to massive fines—or worse, shut down. 

The fix: Automate your guardrails.

JoinedUp prevents non-compliant workers or sites from being scheduled. It’s like having a compliance manager embedded in every shift plan. 

 

4. Relying on manual scheduling & spreadsheets

The mistake: Scaling volume without scaling process. 

Spreadsheets collapse under pressure. Double-allocated workers, missed shifts, overtime miscalculations—manual scheduling just can’t keep up with 10x peak demand. 

The fix: Let your system do the heavy lifting.

JoinedUp’s smart scheduling engine handles bulk rostering, batch edits, and conflict resolution—giving you visibility and control at scale.

5. Failing to engage & communicate with workers

The mistake: Comms breakdowns at the worst possible time. 

Peak staffing requires consistent, centralized, and fast communication. If your team is still using email chains and ad hoc texts, shifts will go unfilled. 

The fix: One place, one system. 

From mobile shift notifications to digital job briefs and check-in tools, JoinedUp keeps every worker in sync—so you can spend less time chasing, more time leading.

Final thought: you can't afford chaos in peak season

The difference between a smooth peak and an operational nightmare often comes down to when and how you plan. 

Don’t wait until the shifts go unfilled or the finance team is putting out fires at 2am. Start now—and give your managers the time, tools, and peace of mind they need to succeed.
