I have to wonder if Tina will be included in the move to the new building or if the company has decided to downsize all the tech writers and being in charge of the move will be Tina's last assignment. Tina should definitely be worried about her job security since she is obviously less important than Asok...or PHB...or Wally.
The reality is that Tina will have to do her regular job AND be in charge of the move at the same time.
However, this is a definite power play time for all. Once the new office space floor plan is either leaked or PHB stupidly puts it up on a hallway bulletin board, offices will be snatched up by PHB and other managers. The managers will have meetings upon meetings to argue about their future office locations and space requirements.
Tina will control the future cubical locations for the employees and be the most powerful person for that level of employees. I also can foresee Wally manipulating the floor plan cad layout to create some sort of dead space as a hide out.
