I mean, I only recommend that someone do this when a company does something as immoral as demanding your previous salary and trying to use it as a negotiation advantage.
Companies shouldn't be doing that, and if they do, well they deserve every tactic to fight right back at them.
That’s the thing about integrity, the lack of it in others doesn’t change your own response.
Interviewer: “What were you making before?”
Interviewee: “Why would that be relevant?”
Interviewer: “I just want to make sure we’re in the same ballpark.”
Interviewee: “Ah, no problem. Tell me the you’re range and I’ll tell you if it’s worth going forward.” (Big smile)
And then the interviewer responds "Haha, No. No job for you."
And then they move on to only interview someone who is will to screw themselves in the negotiation game.
I don't see anything immoral about punishing companies that use sleazy negotiation tactics with your own sleazy negotiation tacts. Kinda like how it is morally ok for police to use force to arrest criminals, even though "force" in general is wrong.
But in this case, replace "force" with "counter sleazy negotiation tactics".
Your stance is equivalent to someone saying "I am a pacifist, and oppose all force no matter the purpose or who it is used against, even if it is the legal authority using the force, or someone using force in self defense." Its negotiation pacifism.
My stance is that I won’t lie. That said, I don’t recall ever being in a position of weakness that would require me to lie either. (It’s easy not to steal if you aren’t hungry.)
This honesty thing is a big deal in life but it isn’t something you can “try out”. It may take decades before it really pays off and when it does, you may not even realize it.
Companies shouldn't be doing that, and if they do, well they deserve every tactic to fight right back at them.
