General legal information, not advice for a specific case. Check current law and the facts of your situation before acting.
Different kinds of leave follow different rules. I’m Attorney Nok, and I would check workplace rules and current law alongside your own leave requests and approvals, rather than treating a balance in an app as the whole answer.
Imagine the HR system shows zero annual-leave days, but you have an email approving a carry-over from a previous period. Save the balance screenshot and the email, then ask HR in writing how the balance was calculated. Keep annual leave, sick leave, and public holidays separate when checking the figures.
Older online guidance may not reflect later legal amendments. Check the rules applicable on the date you plan to take leave, and ask the labour authorities if the calculation remains unclear.
