Key Takeaways:
- Mossadek Ageli received £392,000 for untaken holiday pay.
- He had built up 827 days of unused annual leave since 1998.
- The tribunal also awarded him more than £100,000 for unfair dismissal.
- Sabtina Ltd had agreed that his holiday could be carried over for years.
- The ruling could affect other UK workers with long-running holiday pay disputes.
What Is the Mossadek Ageli Holiday Pay Case About?
The Mossadek Ageli holiday pay case centres on a long-serving estate manager who worked for Sabtina Ltd for almost four decades. During that time, he regularly missed annual leave because the company said it could not operate without him. Instead of taking holiday, he was allowed to build it up and later receive payment for it.
By the time he was dismissed in 2024, he had accumulated 827 days of untaken leave. The company refused to pay him for those days, arguing that there was no valid right to receive such a large amount.
Mr Ageli then brought a claim to the Watford Employment Tribunal, which ruled that the agreement did exist and that the money should be paid.
The tribunal also found that the company had unfairly dismissed him. He had been accused of gross misconduct, but the employer did not properly explain the allegations or allow him to appeal.
| Main Part of the Claim | Amount Awarded |
| Untaken holiday pay | £392,000 |
| Unfair dismissal compensation | £91,490 |
| Basic award for dismissal | £14,070 |
| Total award | £497,560 |
Why Was Mossadek Ageli Awarded Nearly £400,000 for Untaken Holiday?
Mossadek Ageli was awarded nearly £400,000 because the tribunal accepted that there had been a long-standing arrangement between him and Sabtina Ltd. The arrangement allowed his unused holiday to carry over each year rather than expire.
The company had previously paid him for untaken leave in 2001 and again in 2004. Those earlier payments supported his argument that the arrangement was genuine and had been accepted by the directors for many years.
The tribunal decided that his employer could not suddenly refuse to honour that agreement simply because a new board of directors had taken over the business. As a result, the company was ordered to pay the full value of his unused holiday dating back to 1998.
Employment law specialist James Watkins explained: “When an employer has accepted a holiday pay arrangement for years, it becomes very difficult to argue later that it never existed. The tribunal clearly believed there was a consistent understanding between both sides.”
While UK law generally follows a “use it or lose it” policy for annual leave, the Ageli case highlights three specific legal conditions that allowed for a 25-year claim:
- Historical Conduct: The company had already made “lieu” payments of £15,000 in 2001 and 2004, establishing a clear pattern of behavior.
- Explicit Management Approval: A written request to the managing director in 1998 was formally approved, creating a contractually binding variation.
- Prevention of Leave: The tribunal found the employer actively prevented leave by claiming Ageli was “too essential” for the business to function.
Several factors helped increase the final figure:
- He had a high annual holiday entitlement of up to 45 days.
- He had built up leave for more than 25 years.
- The holiday was valued using his final level of pay.
- The tribunal accepted that the unused leave rolled over continuously.
How Did Mossadek Ageli Build Up 827 Days of Untaken Leave?
Mossadek Ageli built up 827 days of untaken leave because he rarely managed to take a holiday during his career. In the early years, he and his personal assistant were the only full-time staff in the business. That meant there was often nobody available to cover his duties.
For two full years, he reportedly took no holiday at all. Between 1988 and 1996, the directors also refused around 200 days of leave. Instead of losing those days, he kept a record of them and expected to receive payment later.
His annual entitlement also became larger over time. It increased from 30 days to 45 days in 1996, meaning that every year added more untaken leave to the total.
| Year or Period | What Happened |
| 1987–1989 | No holiday taken because the business relied on him |
| 1988–1996 | Around 200 holiday days refused by directors |
| 1996 | Annual entitlement increased from 30 to 45 days |
| 1998 onwards | Formal agreement reached to roll over holiday |
| 2024 | Total untaken leave reached 827 days |
This case is unusual because most employees lose unused annual leave if they do not take it within the relevant leave year. In Mr Ageli’s situation, however, the tribunal found that his employer had repeatedly accepted that the days would carry over.
Martin Lewis, founder of MoneySavingExpert, commented: “Many workers assume that untaken holiday simply disappears. This case is different because there was clear evidence that the employer agreed those days could be kept and paid later.”
Why Were So Many of Mossadek Ageli’s Holiday Days Refused?
Many of Mossadek Ageli’s holiday days were refused because Sabtina Ltd claimed that the business could not function without him. He held a senior role and often managed the company’s day-to-day operations from London and Milton Keynes.
The tribunal heard that directors regularly turned down his requests because he was considered essential. In practice, this meant he continued working while his leave built up in the background.
Over time, the refusal of leave became normal within the company. Rather than challenging every decision, Mr Ageli reached an understanding with the directors that the unused days would be carried over and eventually paid.
The situation highlights an important issue in UK employment law. Employers are expected to make sure staff can actually take their annual leave. If workers are prevented from doing so, the employer may later become responsible for paying for those unused days.
Some of the reasons given for refusing his leave included:
- The company had too few staff.
- Mr Ageli was responsible for essential business decisions.
- There was no suitable replacement available.
- Directors believed the business would struggle if he was absent.
What Agreement Did Mossadek Ageli Have With Sabtina Over Holiday Pay?
Mossadek Ageli had an agreement with Sabtina Ltd that any untaken holiday would continue to roll over and would eventually be paid in lieu. He said that he wrote to the company’s managing director in Libya asking for permission to do this, and the request was approved.
After that, he no longer needed to seek formal permission every year. He simply kept a record of the days he had not used. The tribunal accepted that this arrangement remained in place for decades.
The Long-term Arrangement to Carry Over Unused Holiday
The agreement began formally in 1998, although the practice had existed earlier. Mr Ageli said that he gave up holiday because it was difficult to leave the company, and the directors accepted that this created a problem.
Instead of forcing him to take leave, they allowed him to save it. That arrangement suited both sides. The company kept him working, while he expected to receive the value of the holiday at a later date.
The tribunal considered previous payments made in 2001 and 2004 to be strong evidence. On those occasions, he had been paid £15,000 in lieu of untaken leave, showing that the company recognised the agreement.
Those earlier payments made it difficult for Sabtina Ltd to argue that no arrangement existed. The judge concluded that the practice had become part of his employment relationship.
Why did He Expect to Be Paid When He Left the Company?
Mr Ageli believed that if he eventually retired or left the company, he would receive the full value of his untaken leave. He said that there was no company pension scheme, so the unused holiday effectively became part of his long-term financial planning.
He also told the tribunal that he could have authorised the payments himself because he was the company’s sole signatory for many years. However, he deliberately chose not to do that because he wanted the process to remain transparent.
Employment solicitor Rachel Finch explained: “The fact that he could have approved the payments himself but did not was important. It showed that he relied on the agreement rather than trying to create a benefit for himself without permission.”
By 2022, however, a new board of directors had taken control of the company. They questioned the arrangement and later refused to pay the accrued holiday after dismissing him.
| Evidence Supporting the Agreement | Why It Mattered |
| Written request to the managing director | Showed formal approval existed |
| £15,000 payments in 2001 and 2004 | Proved the company had paid before |
| Decades of recorded holiday | Demonstrated a consistent pattern |
| No challenge until new directors arrived | Suggested the arrangement had been accepted |
Why Did the Tribunal Rule in Mossadek Ageli’s Favour?
The tribunal ruled in Mossadek Ageli’s favour because it believed that the company had entered into a genuine agreement and later tried to avoid paying for it. The judge accepted that unused holiday had rolled over every year and that Sabtina Ltd had always intended to pay for it eventually.
The tribunal also decided that the company had not acted fairly when it dismissed him. The employer claimed that he had committed gross misconduct, but it did not provide clear reasons or evidence.
Why the Tribunal Rejected the Gross Misconduct Claim?
The tribunal rejected the allegation of gross misconduct because there was very little evidence to support it. Mr Ageli was dismissed by email in March 2024 and was told only that concerns had previously been raised about his behaviour.
However, the tribunal heard that he had never been properly informed about those concerns. He was not given any warning, did not attend a disciplinary meeting and was not allowed to respond before he lost his job.
The judge said the company did not have a genuine belief that he had committed gross misconduct. Instead, the tribunal suggested that the dismissal happened after the new directors began removing his responsibilities and questioning the holiday arrangement.
Without proper evidence, the accusation could not justify refusing to pay nearly £400,000 in holiday pay.
Why the Dismissal Was Ruled Unfair?
The dismissal was ruled unfair because the company failed to follow even the most basic employment procedures. Under UK law, employees should normally receive written allegations, a chance to attend a disciplinary hearing and the right to appeal.
Mr Ageli received none of those protections. He only discovered that he had lost his job when he was sent an email.
The tribunal found that the process was procedurally unfair because:
- He was not told the exact allegations.
- He was not shown any evidence.
- He was not invited to a hearing.
- He was not given the right to appeal.
As a result, the tribunal awarded him more than £100,000 on top of the holiday pay.
High-Risk Sectors for Holiday Pay Liability
This ruling is a “wake-up call” for industries with high-pressure environments and lean staffing.
Employers in these sectors are now at higher risk for similar claims:
- Family-Owned Businesses: Where formal HR processes are often replaced by informal “understandings”.
- Healthcare and Care Services: Where staff shortages frequently lead to the “essential employee” trap.
- Senior Management: High-level directors who, like Mr. Ageli, manage day-to-day operations and find it difficult to take prolonged absence.
How Much Compensation Did Mossadek Ageli Receive Altogether?
Mossadek Ageli received a total of £497,560. Most of that money came from the unpaid holiday claim, but the unfair dismissal award also significantly increased the final amount.
The full compensation package included:
- £392,000 for 827 days of untaken holiday
- £91,490 for unfair dismissal
- £14,070 as a basic dismissal award
That means the overall figure was close to half a million pounds. For that reason, the case is already being described as one of the most expensive holiday pay disputes seen in a UK employment tribunal.
What Does the Mossadek Ageli Holiday Pay Verdict Mean for Other UK Workers?
The Mossadek Ageli verdict could encourage other workers to review whether they have been prevented from taking annual leave. The case suggests that employers may still be responsible for holiday that was never taken if they agreed that it could be carried over.
However, most workers will not be able to claim for decades of untaken leave unless there is strong evidence of an agreement. The tribunal placed great importance on the fact that Sabtina Ltd had previously made payments and had accepted the arrangement for years.
Employees who believe they are owed holiday pay should keep:
- Copies of leave requests
- Emails or letters from managers
- Records of untaken holiday
- Any evidence that leave was refused
The case may also prompt employers to tighten their policies. Businesses are likely to become more careful about ensuring that staff take leave each year rather than allowing large amounts to build up unnoticed.
Can UK Employees Legally Carry Over Untaken Holiday for Years?
UK employees can sometimes carry over untaken holiday, but only in limited situations. Most statutory annual leave must usually be used within the same leave year. However, there are exceptions if the worker was unable to take leave because of sickness, family leave or because the employer prevented them from taking it.
The Mossadek Ageli case was different because there was an explicit agreement between employer and employee. That agreement allowed the leave to roll over for many years.
Without such an agreement, most employees would struggle to make a similar claim. Courts are unlikely to allow holiday to build up indefinitely unless there is strong proof that the employer caused the problem or agreed to the arrangement.
Could More UK Employees Make Similar Holiday Pay Claims in Future?
More UK employees could bring similar claims if they have evidence that their employer stopped them taking leave or promised that unused holiday would be paid later. Sectors with long hours and staff shortages may be particularly affected.
Senior managers, healthcare workers, care staff and business owners working within family companies may be more likely to face these situations. However, each case will depend on its own facts.
The Mossadek Ageli ruling does not mean every worker can suddenly claim years of unpaid holiday. It mainly shows that if an employer knowingly allows holiday to build up and repeatedly agrees to pay for it later, the courts may decide that the promise must be honoured.
