Part-Time Workers: Your Rights Are Better Than You Think

I used to work with someone who'd been part-time for years. Same job as full-timers, same responsibilities, same quality of work. But she was paid a lower hourly rate, excluded from the bonus scheme, and never got offered training opportunities.

She thought that was just how it worked. It isn't. It's illegal.

If you work part-time in the UK, you have serious legal protections. Most people don't know about them. Let's fix that.

The Law Is Actually On Your Side

The Part-time Workers Regulations 2000 says you can't be treated worse than full-time colleagues just because you work fewer hours.

This means:

  • Same hourly rate for the same job
  • Same access to training
  • Same consideration for promotion
  • Pro-rata benefits (holiday, sick pay, pension)
  • Fair treatment in redundancy situations

"Pro rata" is the key phrase. You don't get the same absolute amount as full-timers – you get a proportional amount based on your hours. That's fair. What's not fair is getting nothing, or getting less than your proportional share.

The Hourly Rate Thing

This is the big one. If a full-time colleague doing the same job earns £40,000 for 40 hours a week, that's £19.23 per hour. You should earn £19.23 per hour too. Not £18. Not £17. The same.

If you're being paid less per hour than full-time colleagues in equivalent roles, that's potentially unlawful. It doesn't matter what excuse your employer gives – "part-timers are less committed," "it's always been this way," whatever. The law is clear. Check your payslip. Do the maths. If something's off, you have grounds to challenge it.

Benefits: What "Pro Rata" Actually Means

Let's say full-time employees get:

  • 25 days holiday
  • £2,000 annual bonus
  • 5% employer pension contribution
  • Private health insurance

If you work 3 days a week (60% of full-time), you should get:

  • 15 days holiday (60% of 25)
  • £1,200 bonus (60% of £2,000)
  • 5% pension contribution (same percentage, applied to your lower salary)
  • Health insurance (this one's usually the same regardless of hours)

Some benefits don't scale – health insurance typically covers you fully or not at all. But anything that can be proportioned should be.

The Training and Promotion Problem

This is where discrimination gets sneaky. Nobody says "we don't promote part-timers." They just... don't. Training sessions are scheduled on your days off. Opportunities go to people who are "more visible."

Here's the thing: your employer should make reasonable efforts to include you. If training is always on Fridays and you don't work Fridays, they should offer alternatives. If you're being overlooked for promotion purely because you're part-time, that's discrimination.

Bank Holidays: The Hidden Unfairness

This one catches people out. Say you work Tuesday to Thursday. Bank holidays are almost always Mondays. Full-time colleagues get those days off; you never benefit.

If your employer gives full-timers 28 days holiday plus bank holidays (36 total), you should get 60% of 36 = 21.6 days. Not 60% of 28.

Many employers get this wrong. They give part-timers pro-rata basic holiday but forget to account for bank holidays fairly. Check your entitlement.

Redundancy: Don't Let Them Target You

When redundancies happen, part-time status cannot be a selection criterion. If you're chosen for redundancy primarily because you work part-time, that's unfair dismissal.

Legitimate criteria include skills, performance, attendance (excluding protected absences like maternity), and disciplinary record. "Works fewer hours" is not legitimate.

How to Know If You're Being Treated Unfairly

Ask yourself:

  • Do full-time colleagues in similar roles earn more per hour?
  • Are you excluded from bonuses or benefits that full-timers get?
  • Do training opportunities always happen on days you don't work?
  • Have you been passed over for promotion despite good performance?
  • Were you selected for redundancy when full-timers with similar records weren't?

If you answered yes to any of these, you might have a problem.

What To Do About It

Step 1: Gather information. Find out what full-time colleagues get. Check your contract. Look at company policies.

Step 2: Ask questions. Sometimes it's a mistake or oversight. Raise it informally first.

Step 3: Put it in writing. If informal conversations don't work, write to HR. You have the legal right to request a written statement explaining why you're being treated differently.

Step 4: Formal grievance. If they can't justify the difference, submit a formal grievance.

Step 5: External help. ACAS offers free advice. Citizens Advice can help. Employment tribunals exist for exactly this situation. You don't need two years' service to bring a part-time discrimination claim. You can do it from day one.

The Realistic Bit

Look, I'm not saying every workplace is out to get part-timers. Most employers try to be fair. But systems and assumptions build up over time, and part-timers often lose out without anyone really noticing.

The point isn't to be confrontational. It's to know your rights so you can spot when something's wrong and address it. Most issues can be resolved with a conversation once you know what you're entitled to.
