“On the employee side, we’re also seeing extremely positive results. We found that people’s wellbeing went up quite a lot: their work stress went down, their burnout rates went down, their job satisfaction went up, their physical health went up, and their mental health went up. Another interesting thing is at the beginning of the trial, we asked them to rate their current work ability compared to their lifetime best as a measure of self-rated productivity, and that went up significantly. People felt at the end of the trial that they were more productive, they just were performing significantly better.”
