Your hours worked are usually sent to us by the company where you work. The processing of the hours and the actual payment almost always take place at the same time each week. If hours or declarations are received after running the first "salary batch", an extra payslip will be generated.
Corrections may have to be made, because the hourly salary or the number of hours was incorrect, for example. This correction will be specified on your payslip of the week in which the correction is made.
