Fifty-five percent of organizations in North America will offer their employees “Summer Fridays” this year, according to a survey by Gartner, Inc. This is a 9% increase from the number of North American organizations that offered Summer Fridays in 2018, and a 43% increase from the number of organizations globally that had similar benefits back in 2012.
