Unless they're going to offer offer an insane buyout, like 1+ years of pay + benefits + some accelerated vesting, nobody who doesn't already have something lined up is going to take this offer. It's much better to stay with one foot out the door and just keep cashing that paycheck and collecting your monthly vest. Especially when you know layoffs are coming, nobody expects you to do anything until they actually pull the trigger, then there's a month or two afterwards where you can slack off because morale is in the toilet, people are still trying to figure out who's left, how the company is organized, which priorities are dead, stuff like that. Ask me how I know.
