How sick leave works
Sick leave is credited yearly or monthly, for example half a day a month, and can often build up to a cap over several years so that employees have a cushion for a serious illness. Advance notice is not practical for sudden illness, so policies ask the employee to inform the manager as early as possible on the day. For longer spells a doctor's certificate is required, and a fitness certificate may be needed before returning after a long illness or surgery. Some employers let the balance go a few days below zero so that a new joiner is not left unpaid for a first illness.
Sick leave versus casual and earned leave
Sick leave is only for health reasons, while casual leave covers short personal needs and earned leave covers planned time off. That is why sick leave usually has no notice rule but a document rule, casual leave has a short cap per spell, and earned leave needs advance notice. Sick leave is also rarely encashable, since it exists to protect income during illness, not to be saved as money. For employees covered by ESI, HR should also understand how ESI works alongside the company's sick leave.
Setting sick leave rules
A clear sick leave rule protects both sides: the employee knows what is expected when unwell, and the manager does not have to judge each case. In ZeniaHR, the default SL accrual is 0.5 day a month, and a leave type can require a document after N days, allow half days, and set how far below zero the balance can go.

Is a medical certificate required for sick leave?
It depends on the company's policy. Most policies ask for a medical certificate only when a sick leave spell goes beyond a set number of days, often two or three. Some also ask for one when sick leave is taken next to a weekend or holiday. A fitness certificate may be requested before rejoining after a long illness.
Can sick leave be encashed in India?
Usually not. Sick leave is meant to protect income during illness, so most companies do not pay it out when unused and instead let it accumulate year after year up to a cap. Earned leave is the type normally encashed. Check your company's leave policy, since a few employers do allow partial encashment of sick leave at exit or retirement.
What is the difference between sick leave and casual leave?
Sick leave is only for illness or injury and may need a medical certificate for longer spells. Casual leave covers short personal matters, like a relative's function or an urgent errand, and is usually limited to a few days at a time. Sick leave often accumulates over the years; casual leave usually lapses at year end.
