But you realize why people fight tooth and nail against these changes, right? It's because looking for a new job is horrible at the best of times. Imagine you've worked at a place for 20, 30 years, are not quite yet at retirement age, but you've been suddenly told that they don't need you, and that you're out on your own. Finding new work isn't easy, and it's not going to get any easier as more jobs go the way of the dodo bird due to automation. There's no guarantee that someone would even be able to find a new job - my grandfather, in 1989, was made redundant in the wake of restructuring at the bus line where he worked after the fall of communism in Czechoslovakia, struggled obscenely to find new work in the small town where he lived, and ended up going into premature retirement at the age of 55, with his fortunes declining accordingly. And that was back when widespread automation was a pie in the sky fantasy!!! Imagine how much worse it would be now, never mind 15, 20, 30 years from now!
Why should the union adjust to the changing times, if the changing of the times means that their membership will be made redundant? That's not the point of a union. As I said before, any sensible worker should be looking out for themselves, in a society that is quite content with throwing them overboard to save a little more money.
