Unpaid leave is time off work that an employee takes without receiving pay and UK law sets out both when it's a statutory right and when it's down to employer discretion.
What is unpaid leave?
Unpaid leave is a period away from work where the employee's contract remains in place but no pay is received. It differs from paid leave such as annual leave or statutory sick pay, where the employee continues to be paid. Some forms of unpaid leave are a legal entitlement (unpaid parental leave, for example) while others depend on the employer's discretion and what the employment contract or company policy allows.
Is unpaid leave a legal right in the UK?
It depends on the type of leave. UK employees have a statutory right to certain forms of unpaid leave under the Employment Rights Act 1996 and related legislation. Others are not legally required but are commonly granted at the employer's discretion.
| Type of unpaid leave | Statutory right? | Notes |
|---|---|---|
| Unpaid parental leave | Yes | Up to 4 weeks per year, per child, for eligible parents |
| Time off for dependants | Yes | Reasonable time to deal with emergencies involving a dependant |
| Jury service / jury duty | Yes | Employers must allow time off; pay is discretionary |
| Public duties (e.g. local councillor) | Yes | Reasonable time off; pay is not required |
| Compassionate / bereavement leave | Partial | Statutory bereavement leave applies in specific circumstances; general compassionate leave is discretionary |
| Career break / sabbatical | No | Entirely at employer discretion |
| Extended sick leave beyond sick pay | No | Depends on employment contract and company policy |
| Time off for medical appointments | No | No legal entitlement; most employers allow it |
| New childcare arrangements / schools settling | No | Often granted under flexible working or discretion |
How much unpaid leave can UK employees take?
There is no single legal limit on the total amount of unpaid leave a UK employee can take. The rules vary by leave type:
- Unpaid parental leave: Eligible employees can take up to 18 weeks per child in total, with a maximum of 4 weeks per year per child. To qualify, employees must have at least one year's continuous service and have parental responsibility for a child under 18.
- Time off for dependants: The right is to a "reasonable" amount of unpaid time in an emergency: typically one or two days. There is no fixed statutory limit.
- Jury service: No fixed limit; it runs for the duration of the trial.
- Public duties: A "reasonable" amount, as agreed with the employer.
- Discretionary leave (career break, extended time off): No legal entitlement. The amount, if any, is at the employer's discretion and should be set out in company policy.
For any unpaid leave outside of statutory entitlements, employers are not legally required to say yes. Employees should check their employment contract and internal policies before making a request.
Do you accrue holiday on unpaid leave?
Yes, in most cases. Statutory holiday entitlement (the legal minimum of 5.6 weeks per year) continues to accrue during unpaid leave, including unpaid parental leave and time off for dependants, and employers should understand how holiday accrual works in practice. The employee's employment status remains unchanged, so UK law treats the leave period as continuous employment for the purposes of holiday accrual.
The exception is where unpaid leave is agreed as a career break or sabbatical that temporarily pauses the employment relationship, which is one form of a broader leave of absence framework. In these cases, the contract should clearly state whether statutory entitlements continue. Employers should take legal advice before structuring extended leave in a way that could inadvertently affect statutory rights.
Pension contributions are also worth noting: employer pension contributions typically pause during unpaid leave periods, though employee contributions on any pay received continue as normal, and HR teams should also monitor the organisation’s overall absence rate and its impact.
Can an employer refuse unpaid leave?
For discretionary unpaid leave, yes, employers can refuse a request, and they are not required to give a reason. There is no legal obligation to grant unpaid career breaks, sabbaticals, or time off for personal reasons unless the employment contract or company policy says otherwise.
For statutory unpaid leave, the rules are tighter:
- Employers cannot refuse eligible employees their right to unpaid parental leave, though they can postpone it (by up to six months) where the timing would unduly disrupt the business.
- Employers must allow time off for jury service and public duties: refusing is unlawful.
- Time off for dependant emergencies cannot be refused where the statutory conditions are met.
If an employer refuses a statutory entitlement, the employee may be able to make a claim to an employment tribunal, and repeated issues around leave misuse may require formal attendance write-ups and documentation.
How does unpaid leave affect employment rights?
Taking unpaid leave does not break continuity of employment, which matters for rights that depend on length of service: redundancy pay, unfair dismissal protection, and statutory notice periods, for example. The employee's job is protected during statutory unpaid leave, and they have the right to return to the same or an equivalent role.
A few specific considerations:
- Sick pay: Employees are not entitled to statutory sick pay (SSP) during unpaid leave. If a period of illness begins during unpaid leave, SSP may become payable once the unpaid leave ends, depending on the circumstances.
- Pension contributions: As noted above, employer contributions typically pause during unpaid periods.
- Employment contract: The contract remains in force. Obligations on both sides (including confidentiality clauses) continue throughout the leave period, and clear no-call no-show rules help distinguish agreed unpaid leave from unauthorised absence incidents.
- Previous employer references: Unpaid leave taken from a previous employer may come up in a reference check. Employees are generally not required to disclose voluntary unpaid leave in job applications, but dishonesty about employment gaps can be grounds for dismissal if discovered later.
How should employers handle unpaid leave requests?
A clear unpaid leave policy saves time on both sides. It should align with a robust employee attendance policy and should cover:
- Which types of leave the company grants beyond statutory minimums
- How far in advance requests need to be made
- Whether requests need line manager and HR sign-off
- How long can be taken at once, and whether there are blackout periods (for example, peak trading weeks in hospitality or retail)
- What happens to pay, benefits, and accruals during the leave period
Apply the policy consistently. If discretionary unpaid leave is granted to one employee in similar circumstances and refused to another, employers face the risk of discrimination claims. Documenting decisions (and the reasons for them) protects the business if a dispute arises.
For shift-based businesses, an absent employee creates an immediate operational gap. Implementing automated scheduling systems can significantly reduce the admin burden and errors when handling these gaps. Shiftbase's absence management feature connects leave requests directly to the schedule: when an unpaid leave request is approved, the shift gap becomes visible immediately and can be filled with an Open Shift before it becomes a problem.
