Read between the lines....
Brown looking in....
Just read the 9/1 statement from the MEC Chairman... He neither endorses or recommends this agreement. He states that he remains "neutral". He also goes on to say that he looks to see the commitment of the group through this vote.
In union-speak he is looking for a strong NO vote so that he can go back to the table and get you what you deserve - - industry leading CBA and no concessions.
Also a less than unanimous 10-4 vote is very telling.
