I was recently asked by a customer whether we could require prospective contractors to hire union labor. I haven't been able to find anything definitively stating the answer, but my instincts say the answer is "no". This is based on the existence of the FAR Part 22 guidance on collective bargaining agreements (CBA). If we could require contractors to hire union labor, why wouldn't we just say that instead of (or perhaps in addition to) requiring new contractors to honor the incumbent's wage rates? Then again, if requiring a CBA or union labor isn't explicitly prohibited, might it be allowable?
Does anyone have any insight on this matter?
