Researchers from Ohio State University’s Fisher College of Business have determined that people are least productive right before a work meeting is about to start. Employees don’t want to start on a big project right before a meeting, so they spend an hour or so doing less productive work, like answering emails. People build “just-in-case” time into their schedules, according to the report, even when there’s no reason to do so. This research might explain why workers feel like they didn’t accomplish a lot during a day with several meetings. One solution to this is for companies to try to stack all their meetings together, giving workers longer, uninterrupted moments to attack bigger projects.
