30 calendar days. A quick note: OFCCP will now tell you that 30 days means 30 days. Don't count on receiving an extension if things aren't ready within the 30 calendar days. Also, an OFCCP compliance officer may contact at some point between now and the end of the 30 days offering technical assistance and asking if you have questions. I would encourage you to be careful with what you tell the compliance officer during this discussion. If you happen to have time, it would be interesting for readers of this site to know what OFCCP office sent you a scheduling letter. There has been remarkably little activity out of most OFCCP offices lately.
You can use this OFCCP audit checklist to ensure you're doing what is required to maintain OFCCP's regulations including VEVRAA, Section 503, and EO 11246. Or request a demo to streamline your compliance and recruiting efforts.
