Closed corporations and employees vanished (White Giant)

Trying to figure out where all my employees went. I close 3 non-profitable corporations and the employees seem to have disappeared. Over 270K low lev workers gone as well as all the others who were at the factories. Anyone know where they went and why?

If you had other corporations that were below 100% hiring, they may have been quickly absorbed. Otherwise, they should show up in your unemployment numbers.
