Pilots ‘folding’ is not the only other option available when held up against the scheduled stop work.
Prior to under taking PIA should one not ask ‘what do we hope to gain and how will this specific PIA achieve it’? The next step is to ask ‘how is my adversary likely to respond and what are the ramifications of that’. If those questions can’t be answered then how well advised is the PIA?
So, two non answers, genuine questions characterised as a threat, and the opposite to these PIA stop works being to ‘fold’. I hope that someone comes up with something better than that!
So what are the other options? Wearing orange ties and making protest PAs has proven to be a waste of time. You can't refuse to work overtime. You can't 'sick out'. The reality is that management are probably not serious about making a deal so the only options are to either take strike action, resign or just carry on with status quo. Even mass resignations has proven to be useless as the government will kindly bring in the military to help out. So I am not sure what other options you have.
