Buffer prides itself on being ahead of the curve. The 84-person social media company has long embraced remote work (it got rid of its office in 2015), salary transparency (it publishes everyone's pay online) and other workplace flexibility options since it was co-founded by Joel Gascoigne more than a decade ago.

When the pandemic hit, Gascoigne saw that employees were stressed gave everyone three-day weekends for the month of May 2020. What started as a month-long experiment has now become a permanent policy, and at the end of 2021, an employee survey found that 91% of workers were happier and more productive with a four-day workweek.
