At the top of the screen there is an "Approve Timesheets" option. All timesheets submitted to the hiring manager waiting for approval will be shown there and can be filtered using the Timecard Start Date dropdown (top).

Click on a name to view the timecard.

You will see a Summary at the top that includes Period, Billable Hours, Non-Billable hours, Total Hours, Total Expenses (If in use), and Status.

The Approve and Return buttons are at the bottom of the form. There is also an optional Comments box available for the Hiring Manager to make notes to the Employee.
