Yes, you have to sign in order to form a valid contract.+ But that's a different part of contract doctrine than consideration. I'd argue consideration is a mostly vestigial doctrine, but contract formalities aren't. In this case, I believe the employee signed, but then tried to argue the contract was invalid for lack of consideration. I don't know if there was nominal consideration recited or not, or what the Hawaiian rule on that is. + Well ... not necessarily sign, but an objective manifestation of intent to be bound, which most of the time means sign.
