To paraphrase a coworker, they demand productivity... but then manage to make the office the most unpleasant, unproductive environment available.
An uncomfortable desk and ancient HP monitors, none of which I can upgrade or change; loud coworkers; tons of unrelated teams, for whom sharing space is unnecessary; and calls with people, most of whom aren't even in the same city (or timezone). Meanwhile I can do all of that at home, more effectively, with far more flexibility.
