Here's the actual study if anyone cares to read it.
Skimming it, a couple things I noticed: This was a study of over 7,000 people across all departments at a large healthcare system. They found on-site workers skewed younger with shorter tenure and remote workers skewed older with longer tenure.
One potential pitfall: They didn't control in any way for department or role, and so floor nurses and housekeeping staff who must work fully on-site are being compared to tenured nurses working utilization review or revenue cycle staff whose job is billing/coding and who don't have to interact with anyone in their roles. In-person and remote jobs in healthcare tend to be very different jobs. I don't know how well this study could be generalized to other types of job settings based on this info
