Below the Belt by Richard Dresser

In a mysterious, undisclosed location in some fictional country, three men work in an industrial compound. Hanrahan and Dobbitt check the products, and Merkin heads the department. They live in a world dominated by corporate bureaucracy, and none of them are sure that they like it.  As they comically maneuver in their pointless quest for status, sinister little animals encroach on the compound.
