TWU 555 WN RAMP /OPS/ PROV and IAM 142 FL RAMP have been meeting since the purchase of FL. TWU has submitted several seniority integration suggestions all IAM has turned down. It decided today since both parties have not been able to reach any solution to seniority integration it needed to go to arbitration. Both parties will meet April 12-16 in Washington, DC with a Federal 3 man panel to propose such integration. With a final ruling expected on/about May 1, 2012. However there is still time for such seniority list to resolved prior to start of such meetings. It would have to be a quick resolution because any proposal would have to have time to be sent out for members to vote on.
