Just because you signed it doesn't mean it is enforceable.
You sign a waiver at trampoline parks that says you won't sue if you hurt yourself or if they cause you to be hurt. The first part covers them, the second part doesn't. If they were negligent or failed to maintain the park and you were injured as a result you can sue them, that waiver is meaningless. [0]
[0] IANAL but I've heard of many cases around these sorts of waivers at parks, rock climbing walls, bounce houses, etc where the waiver is meaningless. They only have you sign it so you think you can't sue them because you signed a piece of paper - and that tactic works.
The second part of their message wasn't there when I responded or I somehow had missed it - which changes the context of my reply. I thought they were making a sarcastic quip.
I totally agree with using the fact you signed away your right to share your salary as a negotiation tool, regardless if it is even legally binding. Hell - I'd argue to say that even if you never actually signed a paper at all.
