Ours is a small organization with 35 employees. Due to market conditions and the current situation, we have issued downsizing letters to some of the non-performers with a one-month notice period. It has been communicated that they are not permitted to take any leave during the notice period, yet some of them are taking unplanned leaves. None of them have any accrued EL (earned leave) balance in their account. Is it permissible to deduct their salary for the unplanned leaves taken?
