This goes beyond freedom of speech. Some of the things you are talking about are protected, and others are you overreaching.Freedom of speech and restriction of employer power should mean that your employer can not intrude and control your personal life just because he fan fire you for no reason and realistically there are no other job opportunities because your country is sh*t (applies less to the most advanced countries).
It means that you can write on your facebook "I am against corrupt judges" and you will not be risking an instant firing by your corrupt boss/employer because he is the one paying for those judges to be corrupted.
It means that you can tell your boss NO when he privately asks to spend an intimate weekend with your daughter in exchange for not firing you.
It means that you can walk out on the street and legally protest against government theft and massive amounts of taxes being stolen through government-private contracts and not risk being fired the next day.
It means that you are not forced to say you agree with what your boss/company is doing because you know you will be fired if you speak your mind.
It means you are not going to be fired because you refused to put your name (signature) on a contract that you know is illegal and corrupt (often when working for corrupt governments, your signature makes you the sacrificial goat if needed).
In the most advanced countries in the world you will never see or hear of any of these problems (or most).
In the sh*tholes it is the DAILY state of life that has not changed for decades and probably will not for many more to come.
