It's really about who has the power, isn't it? There was a time in the post-industrial US when the need for unions -i.e. collective bargaining, legal representation, etc.- was great, as manufacturers abused workers to extremes, threatening to simply replace a complaining worker from the queue of unemployed men waiting outside the fence.
The companies had all the power. They used the power. Then they misused the power. Finally they abused the power.
Now we have unions, who can call for slowdowns, stoppages, and get workers reinstated after being fired, even if they return to work from lunch high as a kite and step in front of an industrial sized piece of machinery.
The unions have all the power. They are using the power. They are misusing the power. And they are of course abusing the power.
Power corrupts.
But don't assume this will continue at Tesla. Among all the paradigm shifts Mr. Elon is sponsoring we may see a change here too. If it is not already so.
There's more to this movement than just the transformation of the transportation industry.
