Administratium has been observed to convert other particles into Administratium. While it has no Atomic charge, it has a strong attraction to productivity field energy. The Administratium particles consume the productivity field and procedes to vibrate in a sympathetic frequency to the productivity field to form a camouflage to appear as large productivity particles. This process will continue until all productivity energy and inertia have been consumed. At some point Administratium particles will merge and combine with other Administratium particles to share and redistribute productivity field energy. If a Administratium particle consumes all itâ€™s productivity field energy, the particle will decay.
I think the more logical answer is that none of the management know his name, so they don't know who to fire. The administrative assistants do, since they schedule the meetings, but nothing is going to happen from that end (read: Carol).
