Adding and editing a worker are very similar functions, and are both performed on the Worker Details Tab. To add a worker, click on the Worker Details Tab. You will notice all the fields are blank, and the button at the bottom right of the form says Add New Worker. To edit a worker, find the appropriate worker. If you do not see the worker in the Worker Details Tab, you can use the Filtering/Searching/Sorting feature to locate the worker. Click the Edit link near the beginning of the row.
Clicking on the Edit link jumps you to the Worker Details Tab. When you are finished making changes, click the Save Changes button. For a detailed explanation of each field, jump to this topic: Worker Detail Page: Explanation of Fields.
