I looked on LinkedIn to see how many employees Mindsense has; the answer was 1-10 (perhaps that's right, perhaps it's wrong, but it's probably in the right ballpark). I'm sure their policy of "0 vacation days. 0 sick days. 0 holidays" works at that scale, where everyone is some sort of lynchpin product manager with a vested interest in the business, but the reality is that, in a larger organisation, there will inevitably be people who are not massively focused on the work at hand, and who treat their job, really, as a means to an end - a way of passing some time between the hours of 9am and 5pm in order to generate enough money to pay their bills and save up for some holidays that they actually enjoy.<p>For a significant portion of those people, offering that kind of flexibility would be a disaster, because they would see it as carte blanche to do as little as they could possibly get away with doing, with as many days sick or on holiday/vacation as they liked. These people aren't motivated by the work they're doing, in any meaningful sense, and they would just as well not be doing it at all if that option were presented to them.<p>Sure, you could say "don't hire those people", but larger organisations need lots of bodies to fill often quite dull jobs, and you can't really afford to treat those people "as adults", whatever that means.
