Talk:Background Employees/@comment-36615844-20180902011014

Michael mentioned in the Pilot episode that Dunder Mifflin has that whole floor of Scranton Business Park, but later we see that Vance Refrigeration is on the same floor. So my theory for the 4 unknown pilot employees is that they worked in the space where Vance refrigeration would be (since we don't see them in the main room or annex) but until Bob Vance bought out that space, the 4 quit or were fired.
