I'm not talking about criminal consequences, for things that are not protected by the right to free speech. I'm talking about consequences in terms of the responses of those around you, to things that are entirely protected by the right to free speech.
Even things that are entirely protected by free speech have consequences. You're perfectly free to mouth off at work about how you don't want to do anything. That's free speech; it's not a crime, you can't be prosecuted. The consequence to your exercising your right in that manner is that your employer decides that you're not a very good choice for a promotion.
Ok so, if you just mouth off at work about not wanting to do your job, but then do in fact do your job, I don't really think it makes sense to be fired for that. And if you don't do your job, well, that's you violating your work contract which you don't have a right to, so yeah of course you'll be fired. If the work also has courtesy guidelines in its contract and you agree to them then you can be fired for that too, but I seriously, seriously doubt some dude griping about hating his job and wanting to sit and do nothing while in a crab fishing vessel out in the wild cold oceans will be getting any sort of consequences for that speech if he does in fact do his job, so this is some sort of bourgeois context where courtesy and feelings matter more than job performance.
See, the thing is, you getting a job is voluntary, you choose to give up some of your rights in the deal. You are not forced to work at a place with any type of limitation, and while most places have some sort of it, you can still somewhat choose which one of those you are comfortable with, so there is no violation there. All there is is a deal being struck. You give up some freedom to earn money and the employers is guaranteed a stable workforce with minimal disruptions or whatever it is. As long as people are voluntarily engaging in it, their rights are not being violated, they're merely choosing not to exercise them to make money, which is fine.
If you strike a deal that in exchange for money you won't exercise your right to free speech, that context is different from one where you didn't agree to anything, yet are socially expected to not exercise it anyways.
It’s not a law (strictly speaking); it’s the police caution that is quoted when making a formal arrest. Similar in principle to the Miranda Rights in the US.
Pretty much this. And even moreso, the way that it is phrased is similar to "You have the right to remain silent, but if you exercise that right and later claim something that can prove your innocence, we are allowed to ask you why you didn't say something earlier."
I mean, it's not the same is it. One is a positive right, "you can remain silent, but if you mouth off what you say counts as evidence", and the other is "if you don't share your proof of innocence right away, without the arcane wisdom of a lawyer to advise you in your phrasing, we will consider that sus", that's a negative right, it puts the onus on the person to know how to phrase their circumstances. Everyone can remain silent and not say anything but a lot of people can't phrase why they're innocent correctly and they are more likely to just screw themselves by saying unnecessary things or may try to lie since they are in a structure where not saying anything is penalized so they are getting themselves deeper in the hole than if they just got caught for that initial crime cause now they lied to the cops too. It's similar but strictly worse.
