Part-time & Fixed-term Worker Rights UK (2026)

Overview

Part-time and fixed-term workers in the UK are covered by two sets of regulations that sit alongside the main body of employment law. The Part-time Workers (Prevention of Less Favourable Treatment) Regulations 2000 protect people who work fewer hours than a comparable full-time colleague.

The Fixed-term Employees (Prevention of Less Favourable Treatment) Regulations 2002 do a similar job for employees on contracts that end on a specific date, after a set period, or when a particular task finishes. Both sets of rules share the same basic idea: your contract type, on its own, is not a lawful reason to pay you less, give you shorter holidays, skip you over for training, or deny you benefits your comparable colleagues receive.

You also keep the standard employment rights that apply to everyone, including protection from discrimination, the right to be paid at least the National Minimum Wage, and access to statutory leave. The regulations do not guarantee identical treatment in every respect, but any difference has to be objectively justified by the employer, not assumed.

Key steps

1. Work out which rules apply to you. Look at your contract and working pattern. If you work fewer hours than full-time colleagues doing similar work, the part-time regulations apply. If your contract has an end date, runs for a fixed period, or ends when a project completes, the fixed-term regulations apply. Some people are covered by both.
2. Identify a comparable colleague. To argue you are being treated less favourably, you usually need a comparator: someone working for the same employer, under broadly similar contract terms, doing the same or similar work. This is the benchmark your pay, benefits, and conditions get measured against. Without one, a claim is much harder to run.
3. Check pay, holiday and benefits line by line. Look at hourly rates, bonus schemes, sick pay, pension contributions, holiday entitlement, access to training, and any staff perks. Part-time workers should receive these on a pro rata basis where relevant. Fixed-term employees should generally receive the same benefits as permanent staff unless the employer can objectively justify a difference.
4. Ask for a written statement if something looks wrong. Both sets of regulations give you the right to request a written statement setting out the employer's reasons for the treatment you have received. The employer must respond within a reasonable time. This statement is useful evidence if you later need to raise a grievance or bring a tribunal claim.
5. Raise it internally before escalating. Most issues are easier to resolve through a conversation with your manager or a formal grievance than through a tribunal. Keep notes of dates, pay slips, emails, and anything said in meetings. If internal steps do not work, Acas early conciliation is the usual next stage before any employment tribunal claim, and there are strict time limits to watch.
