I had 12 months so THEY could pack the crap and paper and furniture crammed into the building and get it OUT also. Anything that is left could be given to some charity before razing the building and erasing its scar from the NYC skyline.
12 hours would be nice. 6 weeks max for the people. Laying on cattle boats or something to ferry them to their new headquarters.
We paid for darn near everything in the building so why are we letting them take it? Just get them out of the country and my heart rate will drop below 100.
