You are able to exclude certain days from being counted when accruing the time off allowance by enabling it in the policy settings.
There is a toggle in the policy settings which will enable you to prevent certain days from counting towards the employee's accrual, an example of this is while an employee is away on unpaid leave they should not accrue holiday days.
You can enable this by going to Settings → Time Off → Policies → select the appropriate policy from the list → Actions → Edit → go to the ‘proration of allowance’ step → toggle on exclude certain days
You can select to exclude paid/unpaid time off requests by policy, or paid statutory/ bank holidays.
When this toggle is enabled there will be an information alert displayed under the "days accrued" tab in the balance activity for the policy.
