Nope; the Guild represents the professional voice of atc. By two bites I guess you mean either Prospect or NATS sending a rep to the same meetings? Prospect acts from a trades union pov (though they do have a memorandum of understanding with Gatco so we consult and work with each other where we may 'overlap'). A NATS rep would be expected to push the NATS line, which as a ppp ansp may not be entirely aligned with the controllers' professional views...
