You can bet:
1) The head of human resources (along with every other "suit" in the company) has her OWN, ENCLOSED office away from the hoi-polloi; and
2) People who successfully stay home a lot (in order to get some "quiet time," did you catch that?) will have their jobs marked for outsourcing.
Does SmartPlanet get kickbacks from cubicle makers or something? Why is there never a piece discussing how horrid it is to work in an "open office"? There is peer-reviewed research proving that it CUTS productivity.
