Generally, though, I'm against the arguments of "automation is bad cuz less jobs". I think that might be true in the very short term, but we're never going to have a case where "all possible work is done", because that's a completely malformed premise. There's pretty much an infinite amount of potential work to do.
The short term matters. It's zero comfort to a factory worker who has lost his job if there will be another, better job for him in a year or two. He still needs to eat between now and then, and he can't buy food with pie in the sky promises of future employment.
The reason for AFAIK, my understanding is it is more common for people to be left behind than to transition entirely to a new industry. (That is my memory of seeing some data around that, not saying I'm correct, but that I find it just as plausible to speculate that industrial transitions don't always transition with the same workers.) Perhaps we should talk farming? That is the biggest example pethaps. Some 80% plus of all populations used to do agriculture. The Grapes of Wraith were all about this very topic.
I wouldn’t necessarily be opposed to forcing companies to pay some amount per month to people whose jobs were automated away for N years, and/or providing job training for a new career.
