Managing casual staff in retail means juggling changing demand, tight margins, and a team whose hours move week to week. To manage casual staff in retail well, you need to get two things right: fair pay and rights, and a rota that works. This guide covers both, in plain UK terms.
Casual and temporary work is a steady feature of the UK labour market. Around 1.6 million people across the UK work in temporary roles, according to the Office for National Statistics (ONS). For retailers, that flexible base often covers weekends, peaks, and seasonal rushes.
Key takeaways for managing casual staff
Casual retail workers may work under zero-hours or other flexible arrangements, depending on their contract and employment status
Irregular-hours casual staff still build up statutory paid holiday, even on zero hours
The Employment Rights Act 2025 sets out proposed reforms, such as guaranteed hours and reasonable notice of shifts, subject to future regulations
Good rotas, clear notice, and inclusive communication can help support a reliable casual team
Get casual workers' rights and pay right
You've probably wondered where casual staff actually stand in law. It's a fair question, because the label "casual" can cover very different arrangements. Getting the basics right protects your people and your business.
What casual and zero-hours workers are entitled to
Casual retail work often uses zero-hours or other flexible arrangements. The exact position depends on each worker's contract and employment status. As the Advisory, Conciliation and Arbitration Service (ACAS) explains, a zero-hours contract has no guaranteed minimum hours each week.
Depending on their status and contract, casual and zero-hours workers may be entitled to a range of protections. Current ACAS and gov.uk guidance sets out the detail. These can include:
the National Minimum Wage (NMW) or National Living Wage (NLW) for the hours they work
paid holiday that builds up from the hours they work
rest breaks and limits on weekly working hours
protection from unlawful discrimination
the ability to turn down shifts they haven't agreed to take
Check the current guidance for how each protection applies to your team. You can also review the current National Minimum Wage rates on gov.uk before you set pay, as rates change most years.
How holiday pay works for casual and irregular-hours staff
Holiday pay trips up a lot of retail managers. Casual staff still build up paid holiday, even on zero hours. The gov.uk holiday entitlement guidance explains how holiday builds up and how to work out holiday pay for irregular-hours staff.
A clear leave management tool can help you record and track holiday as it builds up for each casual worker. It works from the information and rules you configure.
This is general information, not legal advice. Deputy supports compliance workflows but does not guarantee compliance.
Employers remain responsible for determining the employment arrangements and legal requirements that apply to their workers. That includes configuring Deputy appropriately and complying with applicable laws and contractual requirements.
Prepare for proposed Employment Rights Act 2025 changes
The rules around casual and zero-hours work are changing, and you'll want to keep an eye on them. The government has set out reforms through the Employment Rights Act 2025, with much of the detail due in future regulations following consultation. The timing and specifics may still change, so treat this as a heads-up, not a final rulebook.
According to the gov.uk consultation on zero-hours reforms, the proposed changes include:
guaranteed hours for workers who regularly work them
reasonable notice of shifts and of any shift changes
pay for shifts cancelled at short notice
day-one rights from the start of employment
The government has not yet brought these measures into force. Check the gov.uk guidance for the latest position, and take your own advice on how any changes apply to your business. Reviewing your rota and notice habits now can make later changes easier to absorb.
Plan rotas around real demand
Over-staff a quiet Tuesday and you burn margin. Under-staff a Saturday and queues build while your casual team runs ragged. A rota that tracks real demand fixes both problems.
Start with your busiest and quietest patterns, then match casual shifts to them. A rota tool lets you build, share, and adjust shifts from one place, which can help make last-minute swaps easier to manage.
Give casual staff fair notice of their shifts
Casual doesn't have to mean unpredictable. People plan their lives around their shifts, so clear notice can help support engagement and availability. It also lines up with the direction of current Employment Rights Act 2025 proposals.
Demand forecasting uses artificial intelligence (AI) to help estimate how busy a given day might be, drawing on your historical data. Treat these AI-assisted forecasts as suggestions for manager review, then publish the rota with as much notice as you can give.
Recruit and retain a reliable casual base
A casual base can be surprisingly steady if you treat it as more than cover. The trick is to think like someone who works for you. What would make you want to come back next weekend?

The retail workforce is getting younger. Gen Z made up 44% of UK retail shift workers in 2025, up from 39% in 2024, according to Deputy's UK Big Shift Report 2026.
Retention has become a bigger focus, especially as costs climb. In a British Retail Consortium survey, 46% of retail finance chiefs planned to reduce store roles as employment costs rose.
UK employers have also entered a "low fire, low hire" phase, according to Deputy's UK Big Shift Report 2026. The focus now is on retaining existing workers. Clear notice, inclusive communication, and a positive employee experience can help support engagement and retention.
Build a bench of casuals who want to come back
Put yourself in a casual worker's shoes and ask how you rate as an employer. Aim for people to see you as:
an employer people recommend to their friends
a manager who rewards loyal team members with first pick of shifts
a business that trains people well from their first day
someone who runs a fair, predictable rota
Getting these right can help you build a reliable bench of casuals to call on when demand spikes.
