Loss of Pay (LOP) days are unpaid absences from work, including unpaid sick days, leaves of absence, or other uncovered absences. Updating employee LOP days is crucial for calculating wages accurately. It means deducting the appropriate amount from the salary or wages based on the number of LOP days. Accurate tracking of LOP days helps manage labor costs and prevents overpayment for unpaid absences.
The Employee LOP Days page in the greytHR Admin portal enables you to manually update an employee's loss of pay (LOP) days. You can also view the list of employees whose LOP details are already updated. The page displays the employee details such as Name, Join Date, Work Days, and LOP.
