I was specific when I mentioned strike action. Pilots can resign en-masse even today, but it will achieve the same result as that year.
Hence why Australia needs a proper pilots union that can represent all players, or at least an understanding between unions that no pilots will act as strike breakers.
Not sure what a "proper pilots union" is. What the pilot's unions need is a properly funded negotiator who can represent all the unions in any negotiations. One who is not subject to the pressures of being a pilot and who can negotiate with the client's objectives in mind.
