US companies don't trust bottom tier customer service level employees to meet their production quotas unless they are being watched. Many companies are requiring employees to have cameras on their home workstations for those "teleconferences". Activity monitoring software like Toggl along with intrusive, constant text chatting just highlights the "we can squeeze more from these people" at ude American businesses have. As someone who's worked from home for well over a decade, I can tell you that it seems to work well if you have some autonomy. I work for myself so I can plan my day according to my workload. For those who work for corporations, being on a string makes it less so, and it would get to a point for me that I would rather just drive to an office.
There's also the problem of everyone thinking you're free to do their work, because you're not at an office where they can see you're already working on something. When you have multiple parallel pings all day that basically shadows your actual assignments, that can help create the notion that home workers aren't as productive. It's really productivity tracking that needs to evolve to take into account the different environment that work at home presents, from a work standpoint. Then you have the non-working people who think you're also not working because you're at home.
So the industry needs to adapt to work at home, develop for it, not just treat it like an anomaly that they have to find a way to deal with.
