Those studies have already been done, this is yet another study with the same outcomes. People are happier and more productive working hybrid and WFH.

Two studies in early 2022 validated the views of remote/hybrid work advocates. Research from Owl Labs found that remote and hybrid employees were 22% happier than workers in an onsite office environment and stayed in their jobs longer. Plus, remote workers had less stress, more focus and were more productive than when they toiled in the office. Working from home led to better work/life balance and was more beneficial for the physical and mental well-being of employees.

Now the actual results will vary from person to person and some jobs require some level of in person interaction for a variety of reasons including personal preferences for communication.
