To hire part-time, seasonal or temporary staff fast and fairly, plan the dates and shifts first, post a short clear ad with pay and hours, use a quick two-step process (a short application and a 15-minute call or group session), check the right to work, give a written offer with end date and terms, and run a one-day induction. Apply the same fair rules to everyone, and know that part-time and fixed-term workers have legal protections.
Key takeaways
- Work out the number of hours and shifts you need, week by week, before you advertise.
- Use a short process: a simple form, a short call or group session, and a same-week offer.
- Part-time, fixed-term and agency workers have rights. Check the official rules for your country.
- Check the right to work for every person you hire, in the same way.
- Plan induction, safety training and a clear end-of-season message.
Which type of worker do you need?
| Type | Meaning | Common use | Watch out for |
|---|---|---|---|
| Part-time employee | Works fewer hours than a full-time employee in the same business | Regular shifts, ongoing cover | Equal treatment in proportion to hours in many countries |
| Seasonal worker | Hired for a peak period, such as holidays or harvest | Retail peaks, hospitality, farming, events | Fixed-term rules; holiday pay and end dates; some sectors have special permits |
| Fixed-term employee | Employed for a set period or for a specific task | Maternity cover, projects, seasons | Limits on repeated renewals in many countries |
| Temporary agency worker | Supplied by an agency to work for you | Short-notice cover | Agency worker rules; check who is the employer |
| Casual or on-call worker | Called in as needed | Irregular events | Rules on zero-hours or on-call contracts differ by country. Check them |
| Student or young worker | Under 18 or in education | Part-time jobs | Special limits on hours, tasks and pay in many countries |
Choose the type that fits the work. Do not label someone a contractor to avoid cost, because status depends on the facts. See employee or contractor.
What the law says: pointers by region
| Region | Topic | Where to read |
|---|---|---|
| United States | Wages, overtime and youth employment limits under the Fair Labor Standards Act; state laws can add more | US Department of Labor: wages and the FLSA and fact sheets |
| United Kingdom | Rights of part-time workers, fixed-term employees and agency workers; National Minimum Wage and Living Wage | GOV.UK: part-time worker rights, fixed-term employees, agency workers and minimum wage rates |
| European Union | EU directives on part-time work, fixed-term work and temporary agency work; each country applies them in its own law | Directive 97/81/EC, Directive 1999/70/EC, Directive 2008/104/EC |
The key idea in these rules is that part-time, fixed-term and agency workers should not be treated less favourably than comparable full-time or permanent workers without good reason. Details vary. Read the official pages before you set pay and terms. This is general information, not legal advice.
Step 1: Plan the hours and shifts
Create a simple demand plan. List each week of the season and the number of staff needed per shift. Add the minimum and the maximum. Then compute the total hours and the number of people. Compare with your budget. Use the cost worksheet for an hourly cost, including employer on-costs and holiday pay.
| Week | Shifts per day | Staff per shift | Hours per week | People needed (at 20 hours each) |
|---|---|---|---|---|
| 1 | 2 | 3 | 210 | 11 |
| 2 | 2 | 4 | 280 | 14 |
| 3 (peak) | 3 | 5 | 525 | 27 |
| 4 | 2 | 3 | 210 | 11 |
This table is a fictional example. The formula is shifts per day times staff per shift times hours per shift times days open. Write your own. Allow extra people for sickness and drop-outs, and decide how many reserves to keep.
Step 2: Write a short, clear ad
Short roles need short ads. Put the key facts at the top: role, place, dates, shift pattern, pay, and how to apply. Describe the tasks and any training you provide. State how long the application takes. Avoid words that signal age, sex or other protected traits. See how to write a job ad that attracts the right applicants and where to post a job when you have no budget. Good channels include public job services, local schools and colleges, community boards, and your own customers and followers.
Seasonal sales assistant, [shop name], [town]
Dates: [start] to [end]
Shifts: [pattern], [hours per week]
Pay: [rate] per hour plus [holiday pay as the law requires]
Tasks: serve customers, restock shelves, use the till
Training: paid first-day induction
No previous experience needed. We welcome students, parents, retirees and career changers.
To apply: send your name, phone number and the days you can work to [email] by [date]. It takes five minutes. Tell us if you need any adjustment to apply.
Step 3: Use a quick, fair two-step process
- Short form or message. Ask for contact details, availability and one or two job-related questions, such as “Tell us about a time you worked with customers” or “What shifts can you work?”. Do not ask for a long CV for a simple role.
- Short call or group session. A 15-minute call, or a 45-minute group session where candidates do a short task and talk with the team. Use the same questions and a one-page scorecard. See how to run a first interview.
For group sessions, give people clear instructions, offer adjustments, and observe job-related behaviours such as listening, following instructions and working with others. Do not score on style, accent or appearance. Keep a note of each person’s evidence.
| Criterion | What counts | Score 1 to 4 |
|---|---|---|
| Availability | Can work the needed shifts | |
| Reliability evidence | Examples of attendance or commitments | |
| Customer or team skills | Example of working with others | |
| Following instructions | Completed a short task correctly | |
| Interest in the role | Clear reasons that relate to the work |
Step 4: Check the right to work and make the offer
Check the right to work for every person you hire, in the same way, as the law requires. Do not check only people who seem foreign. In the UK, see the GOV.UK right to work check guidance. In the US, employers complete Form I-9 for every new employee; see the US Citizenship and Immigration Services I-9 page. In the EU, rules differ by country, so see Your Europe and your national authority. Our upcoming guide on right-to-work checks gives an overview.
Make a written offer with: role, start and end dates (or the way the end date is set), hours or shift pattern, pay and pay dates, holiday arrangements, notice and what happens at the end. Use the template in how to make a job offer. For young workers, check the rules on age, hours and tasks.
Step 5: Induction in one day
| Time | Topic |
|---|---|
| 09:00 | Welcome, team, tour, schedule |
| 09:30 | Safety: exits, first aid, safe lifting, who to tell about problems |
| 10:30 | Tools: till, scanner, app or whatever the role uses |
| 11:30 | Customer and service standards, with two role-plays |
| 12:30 | Break |
| 13:00 | Shadow an experienced worker |
| 15:00 | Do tasks with supervision |
| 16:30 | Questions, next shifts, who to call if sick |
Give each person a one-page guide with the phone number to call, the dress code, break rules and the main tasks. Pair each new worker with a buddy for the first three shifts. See the onboarding plan for the longer version.
Keep it fair
- Use the same questions, the same criteria and the same time for all candidates.
- Offer adjustments for the process and for the job.
- Pay at least the legal minimum and pay for training time.
- Give shifts fairly and give notice of schedule changes as the law requires.
- Do not promise permanent jobs you cannot offer. If there is a chance of a longer contract, say what the conditions are.
- Do not ask about family plans, health or other protected topics. See what you can and cannot ask.
Finish the season well
Tell staff the end date early. Thank them in person and in writing. Pay all wages and holiday pay due on time. Ask for feedback with two or three short questions. With consent, keep a list of people who would like to work next season. Delete the list on a schedule. A good end to the season makes it easier to hire next year. See how to build a talent pool with consent for the idea.
A worked example (fictional)
This example is invented. A garden centre needs 12 seasonal staff for eight weeks. The owner builds a demand plan, writes a short ad, posts it on the public job service, at local colleges and in the shop. She receives 60 replies in a week. She reads the short forms with a sheet and invites 30 to a group session on two evenings. A manager and a supervisor observe, using the scorecard. They offer 14 jobs (two reserves). She checks the right to work for all 14 in the same way, issues written offers with end dates and holds a one-day induction. Over the season she tracks sickness and schedule changes. At the end she thanks everyone, pays on time and asks eight people if she may contact them next year. All eight agree.
How the demand plan works: the calculation
The fictional table above assumes the shop is open seven days a week and each shift is five hours. Hours per week equal shifts per day times staff per shift times hours per shift times days open. In week 3: 3 shifts times 5 staff times 5 hours times 7 days equals 525 hours. Dividing by 20 hours per person gives 26.25, which you round up to 27 people. In practice you will not get a perfect fit, because people have different availability. Add a column for reserves and plan to over-recruit by a small number, then check actual drop-out against your plan after the first week.
Handling schedules and short-notice changes
Seasonal work often changes at short notice. Weather, sales and sickness all move the plan. Rules on notice of schedules and pay for cancelled shifts vary by place. Some US states and cities have predictive scheduling laws, and the UK and EU have rules on working time and on-call contracts. Check the official guidance for your location. As a good practice, publish schedules at least a week ahead, use a shared calendar or an app that everyone can see, and agree how swaps and cancellations work. Treat requests for time off for school, caring duties, religious observance and medical care fairly and consistently.
| Situation | Good practice |
|---|---|
| Shift swap request | Allow swaps between trained workers with manager approval within a set time |
| Sickness | Give a phone number and a clear rule on how to report; apply sick pay rules as the law requires |
| Last-minute cancellation by you | Follow the pay rules for your country; tell workers as early as you can |
| Reduced hours | Talk to the person and record what you agreed |
| Request for extra hours | Offer fairly, in order of need and fairness, not by favouritism |
Write the rules in one page and give it to every worker on day one. A clear page prevents most disputes. If a dispute arises, listen to the person, check the written terms and take advice if you are unsure.
Frequently asked questions
Do part-time workers have the same rights as full-time workers?
In many countries they must not be treated less favourably without justification, in proportion to hours. Check the official rules for your country.
Can I hire seasonal staff on short notice?
Yes, with a quick process and a written offer. Do not skip right-to-work checks or safety training.
Do I need to pay for training time?
Generally yes, if it is part of the job. Check wage rules in your country.
Can I use an agency?
Yes. Agency workers have their own rules. Check who is responsible for pay, rights and checks.
What if a seasonal worker wants a permanent job?
Treat them as you would any internal applicant, using the same criteria. Do not promise a job you cannot offer.
