In Minneapolis, no garbage is picked up on the holiday. If that was your normal collection day, it’s done the next day instead. If your normal collection day was the day after the holiday, you might be delayed a day, too. Or maybe not. They manage to catch up by the end of the week, because the next week is back on the regular schedule. So during holiday weeks, the workers either work harder, or work longer hours, or they add extra help on those weeks.
