No. Individual personal salary is private information protected by law (at least in our country). Starting salary range in job offers is public, that's not enugh information.
Salaries might be private here, but taxes sure aren't. A recruiter could feasibly walk into the local tax office and ask to see my taxable income for 2020.
Interesting. Taxes and incomes are private in Slovakia for private persons whether they are employed or self-employed or whatever (unless they are a judge or a politician). They are only public for companies.
