A company policy of unlimited vacation is highly regressive and damaging to the workforce as a whole. It obviously creates a situation where it becomes a competition on who takes less vacation time, as an indicator of one’s dedication to the company (whether you think this is a reliable indicator of dedication is irrelevant—all that matters is that many people do think it is, and evaluate others from that perspective).
To avoid this kind of situation, people should be required to take vacation, both to actually get some rest, and to keep a reasonably level playing field for all employees.
