Phoney Strikes
I see on the other thread that the prospect of phoney strikes has been raised. This where a strike is called but not carried out, causing some disruption to the company in making alternative arrangements which of course is the intention in the first place.
One possible weapon that perhaps could be considered to mitigate the effects of this is for non union members and non strikers to register their intention to carry on working with the company. Then if a strike is announced and the "strikers" suddenly turn up for work, the company would be able to say that as they had indicated they were going on strike, alternative cover has been arranged, so they are no longer required for that flight. Send 'em home!
Simplistic I know, but would/could it work?
