> it is expressly illegal for your employer to try and stop you from doing this

Under which statute?

I'm only aware that those clauses in work contracts that forbade talking about your salary were consistently struck down by courts, when they didn't include reasonable limits to the prohibition, because they would restrict you from discussing your salary with your spouse or tax accountant.

Later courts ruled that even with such limitations, those clauses are void, because they run against the basic right of forming coalitions in the workplace (article 9, section 3 of the Basic Law).

But I'm not aware of any statute that bans those clauses expressis verbis. Is there a newish one?

I double checked and you’re right, there’s no specific law but there are a couple court cases where attempts to stop employees from discussing salaries were struck down (for example: https://dejure.org/dienste/vernetzung/rechtsprechung?Text=2%... )
