Any unconsumed leaves (either all or partial) that is carry forwarded from one leave calendar year to the next one, is known as carryover leave. It is totally upto your organisation to define regulations around number of leaves that can be carry forwarded.
Organisations can also decide not to carry forward any unconsumed leave, making it mandatory for employees to consume all leaves by the end of leave calendar year. Some organisations instead of carry forwarding unconsumed leaves, encash it (given that the leave is paid).
In case you are not sure, please refer to your organisation’s leave policy to understand how unconsumed leaves are managed, and setup the same on Keka.
In case of carryover leaves, all the carryover leave are added to your opening leave balance of next leave calendar year.
In case you are having trouble setting to leave carryover on Keka, write to firstname.lastname@example.org.
