> A strike is a particularly clear manifestation of that idea; the employees are saying "give us this, because if you don't we won't work... and you can't just fire us all as it will be catastrophic for you". And it is a powerful manifestation of that, and has a history of working well for the employees. It's worth noting that it was catastrophic for air travel to fire all those people. It had long-term knock-on effects as well, since all the new people hired to replace the people who had been fired later retired within a narrow window of time, creating a staffing crisis. Since there's a mandatory retirement age, this is likely to be a cyclical thing, although there's been recent legislation proposed that would appear to make working past the mandatory retirement age an option for workers. Maybe some workers will jump at the chance to continue in a highly stressful, safety critical position well into their sixties...
