To make sure your remote team stays in touch, have at least a few hours a day of real-time overlap. Working in time zones where there’s no workday overlap at all is tough. If you face that situation, someone might need to shift hours a bit so they start a little later or earlier in the day, so you’re available at the same time. You don’t need eight hours of overlap, though. (Actually, we’ve found it preferable to not have complete overlap—you get more alone time that way.) Two to four hours of overlap should be plenty.
