Answer
A negative Annual Holidays balance usually means annual holidays were taken in advance, an opening balance was entered incorrectly, or leave was entered in the wrong unit.
- If the negative balance is correct, leave it in place and make sure the employer has agreed to the leave in advance.
- If the wrong unit was used, correct the pay if it is still editable. If the pay is completed, use the employer's correction process and add a manual adjustment if required.
- If the migrated opening balance was wrong, add a dated manual adjustment in weeks.
Do not change standard hours or work pattern just to force the balance positive. Those settings affect future leave valuation and conversion.
