After a CO issues an NOV, he or she will attempt to reach an acceptable resolution of the violation findings through voluntary conciliation efforts with the contractor. Conciliation discussions may involve various methods of communication, including the exchange of letters and emails, telephone conferences and in-person meetings. If these negotiations are successful, the CO will document the terms of the settlement in a formal CA. However, if, in the opinion of the CO, the contractor fails to agree to a reasonable settlement, fails to do so in a timely fashion or fails to negotiate in good faith, OFCCP may recommend the case for enforcement. In such circumstances, the CO must prepare a “recommendation to refer for enforcement” package and submit it to the regional office.
