In the Week Summary you can view the status of candidates’ time, approve or request approvals on their behalf, and send reminder messages.
The Timesheets Pending status means the candidate hasn’t yet requested approval. If you click on the Timesheets Pending filter you’ll see both candidates who are yet to enter any time at all (provided a Work Pattern has been set on the Work associated with their placement), and candidates who have recorded time but not yet requested approval.
Approval Pending means the approval has been requested, but the contact is yet to approve the request.
You can tick the box beside particular candidates names, or choose 'Select All Resources' from the menu options, and then either send a new message, approve time, or request approval for the selected resources.
