What nonsense to talk of strike action. Nothing learned from 1989 ? The only pilots with the balls to strike would be those who are financially so independent they would not give a toss about the consequences - legal, financial, career, whatever. The rest even if they were not around in 1989 have enough history on this to know it did not work then and would have even less chance of success now.
A far better course of action and perfectly legal is to work strictly to rule. Light bulb blown in Outer Hicksville? - put it in the tech log. Check every document on the airplane when accepting it - could take two hours to be sure that it's all in order. A nick in a mainwheel tire - better get an airframe engineer out on Sunday to look at it. All in the name of safety, of course, so the legal people would not take you on. Written report to CASA at the 1st sign of pressure. Go on current affairs TV and bag the crap out of the company if any safety issues need airing. Fatigue would be a good start.
And leave the phone off the hook when not rostered on standby, refuse callouts no matter what the financial incentive, make it next to impossible for ops to contact you with roster changes. So many legal ways without the old suicide by strike act.
