This is true in Europe and I guess in any other normal country.

If I stayed to insult my employer (wherever, including social media) they would have the right to fire me.

If I do not agree, I can go to court.

Of course, the nature of my comments matter. If I say that I like the color blue and they do not, they cannot do anything.

If I say that their products suck, they will fire me and the court will agree.

If I say that their products are dangerous (whistle blowing) then they can try to fire me but I will be protected by law.

in germany you have the right to publicly share your own opinion about your employer. you may not insult them, but you may well criticize them or their products, working conditions or anything else that is factually true.

you may also share your political opinions, something US companies seemingly often like to stop, as long as you are not disruptive.
