What would you do?

If after 31 yrs of putting everything you loved into a business and one day you worked all day long and thought everything seemed okay and you look at the clock and thought; "Oh, it's about time to go home." But... at 4PM your boss gathers everyone in one office only to tell all the employees to pack their belongings because the company had gone bankrupt and they were closing their doors to 700 people that day.
