Resend notifications for this JobRequest

If the JobRequest has Preferred Wonoloers, Preferred Notifications will first be resent to those Preferred Wonoloers who have not already accepted the JobRequest.

If the JobRequest does not have Preferred Wonoloers, the available Wonoloer pool will be re-ranked and Wonoloers notified in resulting ranked order.

NB: in both cases, the Wonoloers notified will not necessarily be - and are unlikely to be - exactly the same list as the prior time notifications were sent.
