If the CEO is calling the meeting, you are probably safe. Most CEO's don't have the nads to look people in the eye when they fire them - they get a lowly VP to do it. The lowly VP then calls security who then show up at your desk and escort you out the door sans key/badge/insprirational poster, etc.
Probably just a good brow-beating.
If we don't hear from you, we'll assume he gassed the room because y'all knew too damn much and got Wayyyy to close to the TRUTH!
Somebody check on Pastrami's cat once in a while
Seriously, tho - hope its good news. If not, hey, you can just hang with us all day.
