How leave management works

The process breaks down into five steps, though the complexity varies hugely depending on how many countries and leave types you're dealing with.

  1. Policy definition. HR sets up leave types (annual, sick, parental, unpaid), entitlements per country, and accrual rules.
  2. Request and approval. Employees submit time-off requests. Managers approve or decline based on team coverage and policy limits.
  3. Balance tracking. The system deducts approved days, applies accrual rules, and handles carry-over or forfeiture per policy.
  4. Compliance monitoring. HR audits leave records against statutory requirements to confirm that minimum entitlements are met and no employee falls below the legal floor to ensure every employee meets statutory minimum entitlements.
  5. Reporting. Leave data feeds into workforce planning, absence trend analysis, and payroll.

Calamari's Time Off module automates this across 106 countries, replacing manual spreadsheets with workflows that adapt to local statutory rules.

FAQs

What is the difference between leave management and absence management?

Leave management covers planned, approved time off: annual leave, parental leave, scheduled absences. Absence management deals with the unplanned side: sick days, no-shows, patterns of absenteeism. Most HR teams need both. One handles the requests and balances, the other monitors trends and reduces disruption.

Can an employer refuse a leave request?

Yes, if it conflicts with business needs. But the employee must still get a reasonable opportunity to use their full statutory entitlement within the leave year. Under EU and UK law, employers can adjust the timing of leave but cannot reduce the total. Collective agreements or company policy may add further rules on notice periods and blackout dates.

What happens to unused leave when an employee resigns?

In most EU member states, the UK, Singapore, and Australia, employees are entitled to payment for unused statutory leave when they leave. The employer calculates the remaining balance pro rata to the last day of employment. Leave above the statutory minimum (company-specific perks) may follow different rules, so check the contract and local law.

Do part-time employees get leave entitlement?

Yes, on a pro-rata basis in virtually every jurisdiction. A UK employee working three days per week gets 16.8 days (3/5 of 28). The EU Working Time Directive requires equal treatment regardless of hours worked, and most national laws follow this principle.

Is leave management a legal requirement?

The process itself isn't mandated. But the outcomes it delivers, accurate tracking, statutory compliance, correct pay, are legal obligations everywhere that guarantees accuracy in tracking, statutory compliance, and correct pay are legal obligations in any jurisdiction with paid leave. Get it wrong and you're looking at underpayment claims, labour inspectorate penalties, and tribunal cases.

How does leave accrual work for new employees?

Most statutory schemes accrue leave proportionally from day one. In the UK, that's 1/12 of annual entitlement per month worked. In Singapore, employees need three months of service before becoming eligible. Some organisations front-load the full entitlement on the start date to keep things simple, especially when using leave management software.
