I worked for the owner driver regulator of my country. People would take these jobs that they were making a loss on and not realise and be bankrupt in 6 months
Which goes t to show the mass amount of this happening in India. Ilived there in 2017, drivers didn't understand what Pool was and let everyone out at the first stop.
You can take leave its just not paid. IIrc you can take abscences of up to 12 months due to illness or inury unpaid, before they may be justified in letting you go.
Most jobs have at least:
4 weeks paid leave (annual)
2 weeks sick leave (which may require a note depending on company policy)
12 months parental leave for new/adoptive parents
6 weeks of Long service leave after 7 years, growing at the rate of roughly one week per year thereafter
In addition to this we have 13 days of public holiday
