I loved working from home, it was probably the favorite part of my entire career, but when we did WFH we had to use a remote desktop connection to be able to use all the software necessary to do our job. The connection was slow and dodgy, but during covid times we had a business slowdown so we were still able to keep up with decreased workload. Now that the workload meets or exceeds our pre covid numbers I would hate to try to keep up with customer demands with a slow computer. Another issue for my job is that training new people would be a nightmare.
The good thing is that the we learned that WFH can work for us some of the time. So instead of having to decide if we should take a day off for a snowstorm or a sick kid, we just work from home for a day or two. It's a nice option to have.
