I think you are confused.

Sharing your salary is one thing.

Saying that you are an employee at X company and make X dollars is giving away both your salary and corporate information.

The key is not involving the company. Share your salary as much as you want, but don't go on social media and say 'I work for X' unless you are actually their representative.

A company can’t tell you to not share your salary - it’s protected behavior. Whether you do that over a megaphone in the park or over TikTok they broke the law by firing her.

You can absolutely say "I work for X". Otherwise resumes don't work, forget LinkedIn. Telling people you work for X is not the same as claiming to represent X.

The exception here is executives and maybe in some instances management, where they need to be careful what they say because anything they say may be construed as representing the company. But having on your social media that you work for X and having other posts where you talk about normal social media things? 100% fine as long as your don't say something along the lines of "I work for X and our official policy on Y is..." (i.e. claiming to represent them)
