Gentlemen,
Will you please learn from your colleagues in Cabin Crew, and get professional with your grievances?
Get professional legal and
PR advice. Use the Labour Department as an intermediary, as FAU have done.
Define the issues. Address them individually. Have a strategy.
Set a timescale for agreement or resolution.
Contract Compliance should be the norm in any employment relationship. Very seldom does an employer go beyond his contractual obligations in remunerating you for your contribution to his business.
Sign on as rostered. Use whatever sanctions you can to leverage your position. Given issues of schedule delays, resulting fatigue, stress, sickness potentially affecting both Flight Crew and Cabin Crew, this gives the Captain considerable scope and ultimate total responsibility for the safety of the flight. Commander’s Discretion should seldom be used to extend duties.
Best wishes, as ever.
