Where is the question of doubling the wages for recalled days? There is no logic in paying double. Expenses and wastages should be reimbursed, and there is no question about it.
Balance Days and Encashment Policy
However, balance days should be credited back to his/her account, and the employee can encash at the time of leaving if there is an encashment policy. In this case, the employee must have been paid for the leave days. Normally, all heads are paid for leave availed.
Balance leave must be treated as encashment, and whatever rules applicable for encashment must be applied, not straight double. Some companies do not pay all heads for encashment, and some companies do. Based on the company's policy, the same may be treated as encashed, and the amount paid.
