Seasonal scheduling in food retail

The seasonal calendar of a supermarket

Food retail is one of the sectors most subject to seasonality. Unlike an office where activity is relatively constant, a supermarket experiences considerable footfall variations throughout the year.

And these variations are not a surprise. They return every year at the same dates. Which means they are predictable — and therefore plannable.

Christmas and New Year: the absolute peak

This is the most intense period of the year for a supermarket. The last two weeks of December concentrate a peak of footfall and turnover without equal.

• Sales volume: +40 to 60% compared with a normal week, with even higher spikes on 23 and 24 December.
• Most affected departments: butchery, bakery and patisserie, deli counter, alcohol, chocolate.
• Staffing requirements: +30 to 50% headcount, across all roles: checkouts, departments, stock, logistics.
• Duration: the ramp-up begins 2 to 3 weeks before Christmas. The return to normal happens gradually between 2 and 15 January.

This is also the period of highest cost risk: overtime, public holiday premiums (25 December, 1 January), fatigue and error risk.

Easter: the chocolate and deli peak

Easter is the second seasonal peak. Less intense than Christmas in overall volume, but very concentrated in certain departments.

• Affected departments: chocolate (eggs, figurines, gift boxes), bakery (festive breads and pastries), deli and butchery (celebration meals).
• Timing: the date of Easter changes every year, which complicates planning. The ramp-up begins 10 to 15 days before the Easter weekend.
• Staffing: targeted reinforcements in the departments concerned, rather than across the entire store.

Summer and barbecue: the fresh produce peak

From May to September, demand for fresh products surges: meat for grilling, salads, fruit, cold drinks, ice cream.

• Affected departments: butchery, fruit and vegetables, beverages, frozen (ice cream).
• Distinctive feature: this is also the period of permanent staff holidays. You must both reinforce headcount and compensate for absences.
• Students: the summer holidays are the ideal period for student workers. They are available full-time and cover a large part of the staffing needs.

Back to school: the September rush

The back-to-school period generates a concentrated peak over 2 to 3 weeks in September. In supermarkets, this primarily affects stationery, clothing and food departments (return to regular meal routines after the holidays).

Black Friday and year-end promotions

Black Friday (the last Friday of November) has established itself in Belgian food retail. The major promotional operations leading up to Christmas often start from this date.

• Logistics impact: increased delivery volumes, promotional displays to set up, stock to build up.
• Impact at checkout: footfall up across the whole store.

Preparing the ramp-up: recruiting and onboarding quickly

Every seasonal peak requires additional staff. The quality of your preparation determines whether you experience that peak as a growth moment or as an operational nightmare.

Anticipating recruitment

Do not start looking for casual workers two weeks before Christmas. The good profiles are already taken. Launch your seasonal recruitment at least 6 to 8 weeks before the peak.

• Students: contact them from October for the Christmas period, from February for the summer.
• Flexi-job workers: workers on flexi-job contracts are a valuable resource for peaks. They are already employed elsewhere and are looking for supplementary income. Build your pool in advance.
• Former seasonal workers: your best pool is the people who have already worked for you. They know the store, the procedures, the colleagues.

Express onboarding

A poorly trained seasonal worker costs more than they earn. Prepare a short but effective onboarding process: store tour, role training, safety and hygiene rules briefing, access to the Shyfter app to view their schedule.

In Shyfter, a new team member is created in a few minutes: profile, skills, contract, mobile access. They can view their schedule from day one.

Creating seasonal schedule templates

The strength of a good seasonal schedule is that it does not start from scratch every year. You build on experience from previous seasons.

One template per period

Create a schedule template in Shyfter for each key period:

• "Christmas" template: reinforced staffing across all departments, extended shifts, additional checkouts.
• "Easter" template: targeted reinforcements in bakery, chocolate and deli departments.
• "Summer" template: reinforcements in fresh produce and checkouts, holiday compensation.
• "Back to school" template: gradual return to normal staffing, managing final summer student contracts.
• "Black Friday / promotion" template: logistics and checkout reinforcement for major operations.

Duplicate and adjust

When the period arrives, you duplicate the corresponding template. You adjust team member names, any schedule changes and new constraints. The main structure is already in place. What used to take hours of planning takes a few minutes.

Improving year on year

After each peak, analyse what worked and what did not. Too many people in the textile aisle during the holidays? Not enough in the butchery on 24 December morning? Adjust the template for the following season. Over two or three cycles, your templates become remarkably precise.

Managing your seasonal and casual worker pool

Your ability to handle seasonal peaks depends directly on the size and quality of your flexible worker pool.

Centralising profiles in Shyfter

Create a profile for each seasonal worker, student, flexi-job worker or casual in Shyfter. Record their skills, availability and history. When you need reinforcements, you do not search through an Excel file or rely on memory: you filter by skill, availability and section.

Real-time availability

Your seasonal workers enter their availability directly in the app. You know who is free during Christmas week, who is available on Saturdays and who prefers morning shifts. No more manual collection, no more availability tables that are never up to date.

Last-minute notifications

A casual worker cancels the night before a busy weekend? Send a push notification to all seasonal workers available for that slot. The first to accept is automatically added to the schedule.

Automating Dimona declarations and contracts

During seasonal peaks, administrative volume explodes. Dozens of casual workers and students to declare, contracts to generate, Dimona declarations to send before each shift.

Automatic Dimona

In Belgium, every casual worker or student shift must be declared via Dimona to the NSSO before the shift starts. During a Christmas week with 20 casual workers, that is 100+ declarations to send. Manually, that is an administrative nightmare. With Shyfter, declarations are generated and sent automatically as soon as you confirm the schedule. Zero omissions, zero stress.

Student contracts

Shyfter generates student employment contracts directly from the platform. Hours tracking is automatic, with an alert when a student approaches their annual 600-hour quota. See our dedicated guide on student workers in supermarkets.

Flexi-job workers

Flexi-job workers operate under a specific contractual framework in Belgium. Shyfter manages framework agreements and the associated declarations. See our page on flexi-job workers in supermarkets for more detail.

Post-peak: returning to normal

The end of a seasonal peak is as delicate as its start. Reducing headcount too quickly means understaffing during the transition period. Reducing it too slowly means wasted budget.

Planning a gradual wind-down

After Christmas, do not cut all reinforcements on 2 January. The first week of January still sees footfall above normal (gift exchanges, gift card usage, clearance promotions). Plan a gradual reduction over 1 to 2 weeks.

Contract endings and legal obligations

Seasonal and student contracts have end dates. Ensure all hours are correctly recorded and that end-of-contract documents are ready. Shyfter makes this step easier: the hour history is complete and export to the payroll provider is automatic.

Retaining the best profiles

At the end of each season, identify the most reliable and most capable seasonal workers. Note this in their Shyfter profile. The following season, you know exactly who to call back first.

Controlling costs during peaks

Seasonal peaks are the periods when labour costs can most easily spiral. More headcount, public holiday premiums, overtime, casual workers paid at the hourly rate.

Track costs in real time. Shyfter calculates the forecast cost of your schedule before the week even begins. You can see immediately whether your Christmas schedule is within budget or needs adjustment.

Optimise the contract mix. A student costs less than an agency worker. A flexi-job worker benefits from a favourable tax regime. Combining the right contract types reduces the overall cost of seasonal reinforcements. See our analysis of labour costs in food retail for detailed figures.

Avoid unplanned overtime. This is the main trap of seasonal peaks. A shift that overruns, a casual worker who did not show up, a last-minute reinforcement: overtime accumulates quickly. A precise schedule and an active replacement pool are your best defences.

FAQ — Seasonal scheduling in food retail

When should you start recruiting for the year-end festive period?

Ideally, 6 to 8 weeks before the peak — that is, from early November for the Christmas period. This gives you time to recruit, check availability, train new arrivals and create schedules. Start by contacting your former seasonal workers: they already know the store. Then supplement with new profiles. In Shyfter, you build your seasonal worker pool throughout the year and activate them when the need arises.

How do you create a seasonal schedule without starting from scratch every year?

Use schedule templates in Shyfter. Create a template for each key period (Christmas, Easter, summer, back to school, promotions). Each template defines staffing by department, hours and reinforcement needs. When the period arrives, duplicate the template, adjust names and details, and publish. After each season, update the template with lessons learned. Within a few cycles, your templates become very precise.

How do you manage Dimona declarations during a seasonal peak with many casual workers?

Manually, it is virtually impossible during a peak: dozens of declarations per day, the risk of omission is high, and the penalties for non-declaration are real. Shyfter fully automates the process. As soon as you confirm a shift for a casual worker or student, the Dimona declaration is generated and sent to the NSSO. In the event of a last-minute change (schedule change, cancellation), the declaration is updated automatically. You keep a record of all declarations in the history.
