Would have rather seen a bill also legitimize complete and total lying in response to the question. Answers or claims regarding past salary may not be verified or used as the basis of any employment action.
A bill to legitimize lying would help people who know about it. But the people who most need the help are those who have never heard about this controversy or don't think they have the power in the negotiation to consider lying. The way NYC did it, the law protects the most vulnerable.
True. I edited my response to say "also" thinking about your point. I like my proposal less and less, honestly. I'm personally not a very good liar, so it wouldn't help much.
Also, there's just something that feels wrong about normalizing lying instead of fixing the root problem.
