Please guide me on the issue of leave calculations for contractor employees. We have outsourced contract employees and a provision for a leave encashment policy for them. I have a query regarding this. Generally, leave is calculated as 1 leave for every 20 days present (i.e., 1.5 for a month). Is it calculated like this for a 12-month period as 18 leaves, or is there any other calculation method? Please provide guidelines for the same.
