Click on the Staff tab to view your staff list. Click the staff member to view/edit their record, then click their Jobs tab.
The screen will show a standard job view for jobs assigned to that staff member. However the default view only shows current incomplete jobs and jobs that were marked as completed less than 24 hours ago. Jobs completed more than 24 hours ago drop off the default view as that would often clutter the screen with unnecessary old information. Completed jobs can be viewed by clicking the grey icon above the search box.
