In my case, work from home answered less phone calls, sold less,
and were less responsive than in office workers to my communications. The in and out phone call portion was the easiest to track and WFH was nearly 50% less than in office staff.
It is a very small sample size as I only had 3 people working from home. All of them are gone now and my company is much better off without them. I still allow some work from home options for certain leave situations. It is not likely to come back as an option for all employees. I have 2 employees that can work from home just fine. Neither of them have pets, children, or spouses at home during work hours.
Those getting upset by the conversation are likely good work from home employees. But there are a ton of people who love it because they abuse it.
One of them is now taking orders outside of Chick-fil-a in the middle of Texas. That worked out well for her.
