From the Freep article:

About 700 Little Caesars staffers will work in the new building.
When Little Caesar's moved some of their employees downtown in 1988, the count was 400 employees. I think they pretty much filled the Fox Building at that time. The new building is considerably narrower and probably wont be much deeper. At 14' per floor, it will probably have fewer floor than the Fox. Even taking into account the theatre space in the Fox Building, I suspect it has fewer usable square feet than the Fox.

So, two skepticisms: Will the new building have capacity for 700 employees? Where will these 700 employees come from? Do they actually have that many working in the 'burbs? Sure they may do some new hiring, but 700? Really??
