According to leaked documents tesla actually uses less water than they are allowed to ~450, 000 m^3 vs 1,300,000 m^3. And in the same region there is an asparagus farm that uses double the amount of water that tesla uses.

And no, people don't have to ration their tap water because of tesla

Instead of voting you down, people should explain why they disagreed with you. Because I also don't really get it. I know there's the problem of siphoning drinking water in the region, but besides that the Tesla fab seems better than every single combustion engine fab in Germany, but AFAIK there have never been any significant protests against these.

Edit:

More than 10,000 people work in the factory , so I can't say how they individually feel about the disruptive movement. But I know that the employees were very happy that the conditions at Tesla in the last few months were clarified. They hope that something will happen. No one should have to work in a place where life-threatening accidents happen all the time, where the ambulance comes every day and where accidents are not even reported. We are also committed to changing this.

So I guess the protests want to tackle working conditions there, too.

Edit 2:
Great, now I'm getting down voted too.

The coal companies don't say mean words on Twitter, so clearly they are better than Tesla for the environment.
