You can extend an active Job Post job by clicking on the title from the Jobs Tab to bring you tot he Job Detail page. Choose Extend Job from the Job Actions pull-down menu. If it is within 10 days of the job expiring, you can click on the Extend Now link that appears next to the job expiration date on the Jobs Tab.
NOTE: Extending a job uses one Job Post credit.
When you extend a job, the location of the job must be the same as the current posting, but you can use a job post of any duration.
Attributes of the job (such as confidential listing) and apply process details will also be extended.
If you are using the Direct Apply process, you must have sufficient Direct Apply credits for the extension.
