Hello, Leave means permission to remain away from work. In that case, one of the conditions, i.e., in the course of employment, is not met. The other condition is 'arising out of'. In many cases, although on leave, employees are contacted for work-related issues. If that is so, then an accident while doing the company's work will be considered an employment injury, and the employee will be entitled to compensation.
For example, a driver is on leave in his native place. The company has a parcel to deliver to a place near his native place and to be collected also from another place near his native place. If he meets with an accident while doing that, it will be considered an employment injury.
Every case will have to be examined. No one can say for sure whether an employee is available for accident compensation while on leave.
