New CBA

We have a prime service contract, containing FARs 52.222-41 and 43. The fourth option will expire after September 30. The agency has notified us of its intent to exercise a 6-month extension commencing October 1.

We're negotiating a CBA with the service employees' collective bargaining agent, as the current CBA also expires after September 30. Heretofore, first line supervisors have been covered by the CBA. The collective bargaining agent advised us today that it wishes to drop those supervisors from the CBA which covers the rest of the labor force, but it has offered to enter into a separate CBA for those first-line supervisors.

I believe that both CBAs would have to be executed and submitted to the agency prior to October 1, in order for us to be entitled to price adjustments for wage/benefit increases under the applicable FARs. The agency has been anticipating that we will submit a new CBA for the labor force. I haven't located any requirement in the contract or FARs that would require us to notify the agency if we are going to submit two CBAs rather than the one they are anticipating. Is there such a FAR requirement that I may have missed?
