That has everything to with the employees. WFH is just the excuse.

One thing about WFH is that it exposes such employees. In office, it's easy to look busy and blend in. In fact, you just realized this only now and not when they were in office tells all about it.

There are some cases, like ADHD where body doubling actually helps productivity. So I wouldn’t be surprised if in office productivity was higher for those people.

I also think ADHD is significantly more prevalent among software engineers (mostly inattentive type) in my experience. My random guess would be close to 25 percent:)
