Loss of Pay, or LOP, It can be defined as the leave that an employee takes when they are granted permission to stay absent but do not have adequate leave balance in their account. Employers may allow LOP (Loss of Pay), commonly referred to as Leave Without Pay (LWP), if an employee does not have enough leaves to their credit. An employee would receive a leave of absence (LOP) if their company plans to offer leave and compensate them for that particular workday on a weekend and they fail to show up on both days. Additionally, if a person works on a weekend to finish their work because they are inefficient or lack direction, that day would also be considered LOP.
