EmpCenter is able to calculate overtime for weeks that cross over pay periods.  Since overtime is earned after the 40th hour is worked, the overtime will be paid on the next pay check. 

For example, if you earn overtime the week of October 29th - November 4th, 2017 (as a salaried employee), the overtime will be paid on your December 31st pay check. 

You can always verify when the overtime has been earned by reviewing the results tab on your timesheet to check for the Overtime earned pay code.
