For that reason alone, to answer your question, yes. It is the honourable thing to do in the last defense of yourself and your colleagues.IF your colleagues and friends who have wifes,kids mortgages to pay got sent home with no pay for no good reason you would do what you had to do to get them back.
Now listen very carefully. None of atc wanted to have to do that. Atc had offered for 9 days previous not to strike as long as the people suspended were unsuspended especially since the labour court was to adjudicate in less than 10 days. Whatever the LC were to decide then was fine but why antagonise the situation and suspend people before that. Have you asked yourself that??
If the Iaa and certain people within the upper Iaa hadn't gone a solo run trying to be IBEC Heroes then this would never have happened. Simple. Direct your anger and rightful anger it is, at the Iaa management not the controllers who had no other option except being ridden til kingdom come.
On broader note every section of society uses was leverage they have eg farmers will quite happily drive tractors thru cities all day and release sheep in business and buildings. So what it's what they do. In the last resort when the other side WILL NOT TALK TO YOU no matter what, tell me what are you meant to do in order to stop your friends colleagues and hard working people from people financially and professionally raped by over the top testorone driven meglomaniac gorgon geckos whose only motivation is greed.
All management at iaa earn huge bonuses for doing not much. But as we are getting near end of year those bonuses for management may be n doubt if they can't say we have implemented x ,y and z and so greed may have motivated them into escalation of this dispute which when it cones down to it is over nothing very significant and nothing that couldn't be solved by talking.
