You can go back to the calendar and use the hamburger icon on the top left of the screen and select My Shifts. There are two tabs at the top, Diary and Filters. When you are in Diary you will be able to see the shifts where timesheets have been applied or assigned.

Beside the shift times on any completed assignments you will be able to see the actual number of hours worked (in blue) minus any break times recorded on your timesheet.

You can use the Filters tab to check the status of any shifts you have interacted with. There are five buttons underneath the Diary and Filters tabs. These are Assigned, Pending, Applied, Rejected and Cancelled. Clicking to any of these five options will disable that option for the filtered search.
