iaveight and Direct Bondi are correct in their analysis of the AFA/CWA drive to gain recognition of the NMB, National Mediation Board. The Board's finding that the contracting company was sufficiently close and exercised sufficient control over employee's so as to be indistinguishable from the carrier itself. NMB recognition triggers:
45 U.S. Code § 152 - General duties
First. Duty of carriers and employees to settle disputes
It shall be the duty of all carriers, their officers, agents, and employees to exert every reasonable effort to make and maintain agreements concerning rates of pay, rules, and working conditions, and to settle all disputes, whether arising out of the application of such agreements or otherwise, in order to avoid any interruption to commerce or to the operation of any carrier growing out of any dispute between the carrier and the employees thereof.
This is a huge win for AFA. While it does not guarantee a contract it places Norwegian under the RLA, which at least makes them play by some rules.
