Confessions of a soon to be Laid Off Worker

Okay they called in a meeting at 10:00 AM. Right now it is 8:36 and my tummy is starting to growl. What would you expect in something like this? What I think is that it is either they will lay us all off or just a selected few. How the hell will they decide that anyways? My building alone houses 6,000-7,000 employees and that is not including the security and maintenance people. We know that they have cleared Human Resources, Payroll and IT. But yet my department is the biggest one and all of us right now cant focus enough to continue working. This is the worst position to be waiting for it to be 10 and anticipating the news that they are going to announce to be either good or bad.
