On a similar theme, the only action I have ever seen elsewhere be effectively 'bullet proof' was a pre arranged sick day. You only have to exceed the number of stbys (particularly Capts) available and the wheels begin to wobble gaining the otherwise apathetic attention of your owners. However my guess here is that even if every pilot pushed the button the company, in its arrogance, would fire the lot rather than admit it had made an error. Leaving only one option which is to leave, ranting on here will not change anything and the conditions will continue to deteriorate year on year as we have seen.
Button 1 . Stay and suffer in silence.
Button 2 . Unilateral Sick day and risk termination.
Button 3 . Leave
