Tanda has two ways of preventing leave balances from becoming negative:
Option 1: Preventing leave requests from being submitted that would result in more leave being taken than the employee has available.
Option 2: Using a 'fallback' leave type when an employee requests more leave than they have available.
Both options are configured per leave type in Tanda. You can find these settings by navigating to Time & Attendance > Compliance > Leave Types.
Select the leave type you would like to prevent negative balances for, then scroll down the page to section '4. Advanced Settings' (or section 3 if using Tanda Payroll).
Option 1: Prevent leave requests from being submitted
This prevents employees from submitting leave requests if their request would put them into a negative balance of this leave type.
To turn this on, click the leave type you wish to edit, and turn on 'Prevent negative leave balances'.
When an employee requests more leave than their available balance, the leave request cannot be submitted. A warning will display showing that the balance is insufficient:
Option 2: Allow leave to fall back on another leave type
Leave fall back allows a leave request to be submitted that exceeds the employee's current leave balance. When a manager approves the request, the leave request is automatically split into two requests, ensuring the employee's leave balance does not go below 0 hours.
Turning on fall back leave
To turn on leave fall back for a leave type, select the leave type you wish to edit. Turn ON 'Prevent negative leave balances', and then scroll down to section 4. Leave Rules and choose a Fallback Leave type.
How fallback leave works
When an employee creates a leave request that exceeds the available leave balance, the leave request will be split.
A leave request will be created for the originally specified leave type, and will use the remaining balance the employee has. A second leave request will be made for the Fallback leave type, at the length remaining from the leave request.
In the example below, Unpaid Leave is the chosen fallback leave type for Annual Leave.
This employee had 1.875 hours of Annual Leave, but requested 7.6 hours off. Once the request was approved, it allocated the available 1.875 hours to Annual Leave, and the remaining 5.725 hours to Unpaid Leave:
