I don't think there are successful examples of unions being able to fight major technological shifts in the long haul. At best, they can force the management to accept a suicide pact - we're all slowly going down together. That may be preferable to sudden layoffs, but it's still not great, as evidenced by the troubles of the US auto industry. Instead, I think that doctors and lawyers have it right: they effectively have the authority to decide who's allowed to practice the profession, so ChatGPT can't write you prescriptions or defend you in court.
