During pandemic there was published paper (in nature?) that collected and analyzed thousands of employee data and arrived at same conclusion. It’s hard to stay disciplined when working remotely, apparently. However, I don’t think remote-only startups suffers from same issue. Moving traditional office employee to remote suddenly would be problematic unless there was a proper training for setting up home office, meeting etiquette, setting up cultural expectations etc.
