Yes. Loss of pay (https://blog.managetrix.com/lop-full-form-meaning-leave/) is when an employee uses leave that does not fall under the scope of available paid leave and/or is not on approved paid leave. The employer withholds the corresponding amount from the payroll according to the payroll policies. Employees can make better planning decisions about leave when they have an understanding of loss of pay, and will be better equipped to avoid unexpected deductions.
