Maxine is offered an early retirement incentive in exchange for her signing a waiver of any ADEA claims she might have, arising out of the early retirement plan. She is presented with the offer on June 9, 1997, and told she has until June 13 to accept the offer and sign the waiver. She signs the waiver on June 11 and later wishes to bring an ADEA claim based on some aspect of the early retirement plan. Will the waiver preclude her claim? Explain.
