    Understanding Leave Balances and Accruals

    How Balances Work

    Every employee assigned to a leave policy has a balance that tracks how much time off they have available. The balance changes through:

    • Grants: Initial or annual allowance given to the employee
    • Accruals: Time earned gradually over pay periods
    • Usage: Time deducted when time-off requests are approved
    • Adjustments: Manual corrections made by an admin
    • Carryover: Unused time that rolls into the next year
    • Reversals: Corrections that undo a previous transaction

    Balance Types

    Balance-Based Policies

    Employees receive a fixed allowance (e.g., 15 vacation days per year). The full amount is granted at the start of the year or when the policy is assigned.

    Accrual-Based Policies

    Employees earn time off gradually. For example:

    • 1.25 days per month = 15 days per year
    • Accruals happen automatically based on the policy's frequency (monthly, bi-weekly, etc.)

    CrewHR runs accrual calculations automatically. You do not need to manually grant accruals.

    Tracked Policies

    Tracked policies record time off without maintaining a balance. This is common for unpaid time off where there is no limit on usage.

    The Leave Ledger

    Every balance change is recorded as a transaction in the leave ledger. This provides a complete audit trail.

    Viewing the Ledger

    As an admin:

    1. Go to Time Off and select an employee
    2. View their policy assignments and balances
    3. Click to see the ledger history

    As an employee:

    1. Go to Time Off in the employee portal
    2. Click History on any balance card

    Each ledger entry shows:

    • Date of the transaction
    • Type (grant, accrual, usage, adjustment, carryover, reversal)
    • Amount (positive for additions, negative for deductions)
    • Running balance
    • Notes or context

    Manual Adjustments

    Admins can manually adjust an employee's balance when needed:

    1. Navigate to the employee's leave balances
    2. Click Adjust Balance
    3. Enter the adjustment amount (positive to add, negative to deduct)
    4. Add a note explaining the reason
    5. Save

    Common reasons for manual adjustments:

    • Correcting an error
    • Granting bonus time off
    • Adjusting for a policy change
    • Accounting for time off from a previous system

    Carryover

    At the end of the year, carryover rules determine what happens to unused time:

    • No carryover: Unused time is forfeited. Balance resets to zero.
    • Limited carryover: A set number of days or hours carry over. Any excess is forfeited.
    • Unlimited carryover: All unused time carries forward.

    Carryover is processed automatically by CrewHR based on the policy's carryover settings.

    Carryover Expiry

    Carried-over time can have an expiry date. For example, "Use carried-over time within 3 months of the new year." After the expiry, any remaining carried-over time is removed.

    Reversals

    If a transaction was made in error, admins can reverse it:

    1. Find the transaction in the ledger
    2. Click Reverse
    3. A new transaction is created that undoes the original

    This is cleaner than deleting transactions because it preserves the full history.

    Tips

    • Check balances before approving requests: Verify the employee has sufficient balance
    • Document manual adjustments: Always add a note explaining why when making adjustments
    • Review carryover settings annually: Make sure your carryover rules still match company policy
    • Use the ledger for disputes: If an employee questions their balance, the ledger shows every transaction
