This drama is getting ridiculous. HQ2-1, and HQ2-2? What does HQ even mean then? Even if they are called HQ, it is hard for me to imagine they can function as one.
This is true of any large corporate campus -- 25,000 people at one site are not one cohesive unit, there are plenty of competing projects.
And you still end up using video conferencing even with people in the same campus because no one wants to take a 15 minute walk to the building on the other side of campus for a 30 minute meeting.
