Two days of either c leave or p leave taken along with declared holidays will be taken as additional leave days say as in this as c leave (Casual leave) on sat and Monday will be considered as 3 days leave and Sunday will not be considered as a company holiday. but in case a candidate takes a casual leave and a sick leave on Saturday and Monday respectively, then the leave taken by employee will be only two days as then Sunday will be a company holiday. Similar rule applies to weekly off pre and post leave days. This is for your kind info
