Great Q and a timely one--even if I wasn't so timely in answering it :(   What you're talking about is a concept known as pay transparency and I think it's poised to become the next big thing in HR law. Last month, Ontario became the first province to adopt a pay transparency law, which takes effect on Jan. 1. Among other things, the law bans employer reprisals against employees for discussing salary with each other. (I believe the protection also extends to job applicants.) And a policy banning such info sharing would, of course, be unenforceable. But that's Ontario only. At least for now. I'd be quite surprised if other provinces, maybe even Alberta, adopted their own pay transparency laws some time in the not too distant future. But it hasn't happened yet. Hope that helps. Glenn
