This happens far too often, so I decided to give you some insight ……………..
If every person in your business is on the same employment contract, or worse, no written contract at all, you’re carrying a risk you probably haven’t priced in.
Small and growing businesses rarely have a neat, uniform workforce. You might have full-time employees, part-timers, casual weekend staff, an apprentice, a self-employed contractor doing your marketing, and agency workers covering peak season. Each of those people has a different legal status, different rights, and different obligations on you as the employer, and that means they need different contracts, different onboarding, and different management.
Get it right, and you stay compliant, avoid tribunal claims, and — just as importantly — keep hold of good people. Get it wrong, and the cost can be eye-watering.
Here’s what you need to know.
Not Everyone Who Works for You Is an “Employee”
UK employment law recognises three main categories of working people, and the differences matter enormously:
Employees have the fullest set of rights — protection from unfair dismissal, redundancy pay, statutory sick pay, family leave, and more. They work under a contract of employment with mutual obligations: you provide work, they do it.
Workers (including most casual and zero-hours staff) sit in the middle. They’re entitled to the National Minimum Wage, paid holiday, and protection from discrimination — but not unfair dismissal rights or redundancy pay.
Self-employed contractors are in business for themselves. They have very few employment rights against you — provided they’re genuinely self-employed.
Here’s the catch: status is determined by the reality of the relationship, not the label you put on it. Call someone a “contractor” while controlling their hours, providing their equipment and requiring personal service, and a tribunal can decide they were a worker — or an employee — all along. That’s when back-dated holiday pay, unlawful deductions claims and unfair dismissal exposure land on your desk in one go.
Different Contracts for Different People
Every worker type needs paperwork built for the relationship you actually have:
Permanent employees need a full contract of employment covering hours, pay, notice, holiday, sickness, and — since April 2020 — a written statement of particulars from day one. This is a legal requirement, not a nice-to-have. A well-drafted contract also protects your business with confidentiality clauses, notice provisions and, where appropriate, post-termination restrictions.
Part-time employees need the same contract quality as full-timers, and pro-rated benefits. Treating part-timers less favourably than comparable full-timers is unlawful unless you can objectively justify it.
Fixed-term employees need a contract with a clear end date or completion event, and remember, successive fixed-term contracts beyond four years can convert to permanent status automatically.
Casual and zero-hours workers need a worker agreement that honestly reflects the casual arrangement: no obligation to offer work, no obligation to accept it. If in practice they work regular hours every week, the “casual” label won’t survive scrutiny, and reforms under the Employment Rights Act are tightening the rules on zero-hours arrangements, including rights to guaranteed-hours offers and reasonable notice of shifts.
Apprentices need an apprenticeship agreement that meets statutory requirements, get this wrong and you may have created a traditional common-law apprenticeship, which is significantly harder and more expensive to end.
Contractors and freelancers need a genuine consultancy agreement, not a reworded employment contract, plus a hard look at IR35 if they operate through a limited company.
Agency workers are employed by the agency, but after 12 weeks they’re entitled to the same basic pay and conditions as your directly hired staff, so your obligations don’t disappear just because the payroll sits elsewhere.
Onboarding: Where Compliance Meets Retention
Onboarding isn’t just a pile of forms, it’s the moment a new starter decides whether they’ve made the right choice. Research consistently shows a strong onboarding experience dramatically improves retention, while a poor one has new hires quietly re-opening the job boards within weeks.
But onboarding also needs to flex by worker type:
- A permanent employee needs the full experience: right to work checks, contract issued day one, induction, policy briefings, a structured probation period with proper reviews, and a clear line manager relationship from the start.
- A casual worker needs streamlined onboarding — right to work checks and health & safety are non-negotiable, but a six-month probation framework makes no sense for someone doing occasional shifts.
- An apprentice needs onboarding built around their training plan, with time set aside for off-the-job learning and a manager who understands the commitment.
- A contractor shouldn’t go through employee onboarding at all — putting a freelancer through your induction, appraisals and staff handbook is exactly the kind of evidence that blurs their status.
One rule never changes: right to work checks apply to everyone before they start. Illegal working penalties now run to £45,000 per worker for a first breach and £60,000 for repeats. No contract type exempts you.
Managing Different Workers Differently
Day-to-day management should track legal status too:
- Probation periods — use them properly for employees, with structured reviews and honest conversations. A probation that nobody manages is a wasted protection.
- Performance management — full appraisal processes for employees; lighter-touch check-ins for casual staff; outcome-based reviews (not performance management) for contractors.
- Absence and holiday — workers accrue holiday too, and casual staff holiday must now be calculated correctly following changes to rolled-up holiday pay rules. Getting this wrong is one of the most common — and most claimable — errors we see.
- Ending the relationship — dismissing an employee needs a fair process; ending a casual arrangement or contractor engagement follows the contract. Confuse the two and you either overcomplicate a simple exit or expose yourself to a claim.
Why This Matters More Than Ever in 2026–27
The Employment Rights Act reforms are transforming the landscape. Most significantly, from January 2027, the two-year qualifying period for unfair dismissal protection is expected to drop dramatically, meaning employees will gain protection from unfair dismissal far earlier in their employment.
That changes the maths completely. The informal “let’s see how it goes” approach to new hires — vague contracts, unmanaged probations, no paper trail — becomes genuinely dangerous. Businesses that get their contracts, onboarding and probation management right now will be the ones that adapt smoothly. Those that don’t will learn the hard way, one tribunal claim at a time.
The Retention Dividend
Here’s the part that often gets missed: compliance and retention aren’t competing priorities, they’re the same project.
Clear contracts mean people know where they stand. Proper onboarding makes new starters feel expected and valued. Fair, consistent management builds trust. The businesses that hold on to good people are almost always the ones with their HR foundations in order, because people stay where they’re treated properly, and treating people properly starts with getting the basics right.
