- Accrual
- Earning leave gradually over the year, for example a fixed amount each month or pay period, so the available balance rises over time.
- Blackout period
- A defined window during which leave requests are restricted, used to protect critical business dates such as a peak season.
- Carry-over (rollover)
- Unused leave balance that moves from one cycle into the next, often with a cap and an expiry date so it does not accumulate indefinitely.
- Coverage rule
- A minimum-staffing constraint per team that prevents approving a request which would leave the team below the required headcount on a given day.
- Effective policy
- The single policy that actually applies to an employee after inheritance is resolved across user, tag, team, department, and location.
- Lump-sum (front-loaded)
- Granting the full annual allowance at once, usually at the start of the year or on a work anniversary, so the entire balance is available immediately.
- Proration
- Adjusting an entitlement to a partial period, for example for a mid-year start or a part-time schedule, so the amount matches the time actually covered.
- Tag (replacement vs additive)
- A segmentation label that adjusts policy for a group of people; in replacement mode it overrides the inherited policy, in additive mode it stacks extra days on top.
- Tenure tier
- Extra leave granted based on length of service, so longer-tenured employees receive a higher allowance under the same policy.
- Waiting period
- A delay after a grant or a new hire's start date before leave can be used, common with accrual models for new employees.
