Hi,
leave policies are almost always similar in most countries, even with developing countries like ours. However, what most fail to incorporate in the formulation of these policies is the angle of retention.
Attrition is one of the greatest concerns across industry, and by increasing the leave credits as the tenure of an employee grows may minimize the problem. It doesn't have to be a big increase but it will give employees something to think about if they are planning to find employment elsewhere.
I've been conducting surveys to confirm this and the results are positive
