We break them. Take your colleagues out to lunch and explain that in order to determine if there is any on-going wage discrimination that you think that the group should share their salaries with each other, and that you're willing to go first if they agree to share their salaries as well. Follow up by posting your salary to GlassDoor. My understanding of the law in my country is that discussing salaries for the purpose of preventing wage discrimination is explicitly legal, but this is not legal advise and I likely do not live in your country. Edit: The group you take our to lunch should not include your supervisor/boss. For some reason my experience tells me that they view this as undermining behaviour no matter how you broach the subject.
