Tesla will allow a union the same time mcdonalds or starbucks allows a union.

We can pretend unions will solve the problems but the reality is regardless of what any worker wants their jobs are going to be automated so it needs to be a group effort to force the allowance of free re-education/re-training into a different profession (i.e. UBI with stipulations that you must retrain into a new job until all jobs are automated).

There are no other options and you can’t expect a company to keep a position open for a human that needs breaks, sleep and to eat when their competition is automating fully and saving more money than they are because they were forced to or chose to keep humans on staff.

This is not the age where unions have any effective impact, especially when almost every job available today will be eliminated in the next decade through direct mechanical automation or AI automation.

The only thing unions can do is push protectionism and that will kill the economy by killing companies and then we lose the companies, the tax revenue AND the jobs.
