How would you remove any kind of negotiation though? Say that it's illegal for an applicant to say "You have to pay me X or I won't accept the offer"? Or for an employee to say "Give me a raise of Y, or I'm leaving"? What if they already have an offer from a different company for more money? Can they tell their current employer? And if they do, can the employer offer to increase their wage to keep them? And if they can't, can they offer the employee a "new" higher paid position so it technically isn't a raise/negotiation?
