Not many workplaces have "summer Fridays" -- that genteel tradition of closing down around lunch once a week from Memorial Day to Labor Day. According to a survey done by Ultimat Vodka, just 12 percent of employed adults get this perk.
Officially, that is. Because anyone who's tried to start a new project or close a deal on a summer Friday has probably noticed that, well, not much gets done. People are slipping out.
