Click on your To-Do Bell to see your list of My To Do Items. Submitted timesheets will show up in your list as Approve/Reject Timesheet. Click on that To-Do Item to view it.  Verify that the pay period date of the timesheet coincides with the pay period you're working on.   If you wish to view the timesheet to verify the accuracy, you may click on the Open Timesheet link.  At the bottom of the screen, you have the options to Reject or Approve the timesheet.   If you reject it, you have the option to provide a comment informing the employee the reason for the reject and what they need to correct before re-submitting.
