Calculate Extra Earnings Per Week

Hello,

I have a list of a few hundred employees.How can I find out how much an employee earned for the extra hours they worked during a week? The week in this case starts on Sunday and end on Saturday.


The employee has a set number of hours they are scheduled to work each week, however, they may work more than their regular scheduled hours during that week. So how can I find out exactly how many extra hours they worked (beyond their regular schedule) and how much "extra" money they earned?


Thanks,
Ceara
