Apart from EL, some companies also provide a leave type called Casual Leave. Such leaves accommodate any urgent/ unforeseen personal requirements as against EL being planned leaves.
Urgent plumbing issue at the house? Take half or full day of CL and get the problem sorted out. Need to go to the kid's school for some admission related work? CL comes to the rescue.
Providing this type of leave is mandatory in many states, but not so in some other states. There is a combined entitlement for CL and SL (sick leave) in some states like Delhi.
If CL is not mandatory for your business, EL can equally serve the purpose. It reduces the number of leave types and simplifies the leave policy.
