Who ever was negotiating for mgt had aag authority, they were instructed on the boundaries that limited their negotiation authority, so I dont believe envoy went beyond what aag instructed. Envoy mgt has no balls to go against aag, so I dont believe their excuse.
It's just drag it out any way to see if the mec comes back with a lower request. Mec should not give up what was already agreed to. Mec should do a media blitz.
