Annual leave is essential for employee wellbeing, effective performance and sustainable workforce planning. However, it can become a significant operational challenge when employees build up large balances and seek to take them during the busiest part of the year. This is particularly relevant in sectors with seasonal peaks, such as hospitality, retail and leisure, where demand often rises sharply in the run-up to Christmas.
A planned, year-round approach helps employers meet their legal responsibilities, treat employees consistently and protect service delivery. HR should not wait until the final months (now) of the holiday year to identify a problem. Regular monitoring, clear communication and timely intervention should form part of normal workforce management.
Understanding the statutory entitlement
Most workers in the UK are legally entitled to 5.6 weeks’ paid annual leave each holiday year. For someone working five days a week, this is normally 28 days. Bank holidays may be included within that entitlement, depending on the contract. Part-time workers receive the same 5.6 weeks on a pro-rata basis, while entitlement for irregular-hours and part-year workers is calculated under the rules applying to their working pattern.
Paid annual leave is a legal right, not simply a benefit that an employer may withdraw when operations are busy. Employers can control when leave is taken, refuse particular dates for a genuine business reason and restrict leave during defined peak periods, provided the contract or holiday policy supports this approach and the applicable notice requirements are followed. However, they cannot prevent workers from taking their statutory entitlement altogether.
Employers also have a responsibility to provide workers with a genuine opportunity to take their leave. Where an employer has not allowed or encouraged a worker to take all their holiday, or has not made clear that untaken leave may be lost and not carried forward. Different carry-over rules can apply where leave cannot be taken because of long-term sickness or statutory family leave. HR should therefore review the individual circumstances rather than automatically applying a “use it or lose it” rule.
Create a year-round holiday plan
Holiday management should begin at the start of the leave year. HR should publish the holiday policy, confirm the leave-year dates, explain how requests will be prioritised and identify any periods when leave will be restricted. Employees should be encouraged to plan ahead, particularly if they need time off during school holidays, religious festivals or other high-demand periods.
HR should review balances at regular intervals—monthly in larger or seasonal businesses, or at least quarterly elsewhere. A simple communication cycle might include a reminder at the end of the first quarter, a mid-year balance statement, targeted messages to employees with high balances and a final review well before the peak period. Managers should receive reports showing who has taken little leave and be expected to discuss plans during one-to-ones.
HR should also look for practical barriers. Employees may believe workloads are too high, fear that taking leave will reflect badly on them or repeatedly have requests declined. Managers should be reminded that encouraging leave is part of responsible people management. Cross-training, planned cover and earlier allocation of work can reduce dependency on individuals and make regular breaks easier to accommodate – HR can provide guidance on these workforce planning processes.
Prepare early for seasonal pressures
For hospitality and other seasonal businesses, the final quarter should be planned months in advance. HR and operational managers should forecast staffing needs, define minimum cover levels and decide whether any blackout periods or limits on simultaneous leave are necessary. Restrictions must be reasonable, communicated early and applied consistently. A blanket refusal introduced at short notice is more likely to damage trust and leave employees with insufficient time to use their entitlement.
By late summer or early autumn, employees should receive individual confirmation of their remaining balance, the deadline for submitting requests and any restrictions that apply. Those with substantial untaken leave should be asked to propose dates across the remaining months. Where requests conflict, HR should apply the published process fairly rather than relying on informal preferences. Possible solutions include rotas, partial approval, splitting leave across weeks or agreeing alternative dates.
If voluntary planning does not resolve a high balance, an employer may require a worker to take leave, subject to the contract and the statutory notice rules. The default position is that the employer should give notice at least twice the length of the leave it requires the worker to take. HR should act early enough for this to be meaningful, seek mutual confirmation, then confirm the arrangement in writing and avoid directing leave at a time when the worker cannot genuinely rest.
Practical steps for HR
- Maintain accurate, up-to-date holiday records for every worker.
- Set review points throughout the year and send written balance reminders.
- Train managers to encourage leave and escalate consistently high balances.
- Publish peak-period rules and request deadlines well in advance.
- Assess requests fairly and document the business reason for any refusal.
- Offer alternative dates when a request cannot be approved.
- Review sickness, family leave and employer-related barriers before deciding whether leave can be carried over.
- Monitor patterns across teams to identify workload, staffing or cultural issues.
- Include expectations in the holiday clause within the employment contracts.
Effective holiday management balances legal compliance, employee wellbeing and operational resilience. The most reliable approach is consistent communication throughout the year – not a last-minute warning in December (or when you have your holiday year end). By monitoring balances, addressing obstacles and planning for seasonal demand early, HR can help employees receive and use their entitlement while ensuring the business remains properly resourced during its busiest periods.
