Meanwhile, here in Belgium, some companies force employees to come to the office despite government plea to allow remote work. Subjectively, there's been much less traffic on the streets in the beginning of the pandemic. Now, it seems like far too many people are still commuting every day.
You are completely right, some employers just can't cope with the tiny bit of control they lose when their employers work from home. A friend of mine (who is also in IT) still has to do an hour and a half drive 3 times a week just so that a client can 'see' that he is working. There is no reason for him to go work there, other than inspection. We're in IT, all we need is a decent computer and a network connection.
It won't be for everyone but there has still been a huge revolution. Many businesses didn't even have laptops for employees before. Having the technical infrastructure makes it much easier to allow 1-2 days per week from home.
I've also seen WFH advertised much more in job ads. That in turn probably means that more candidates ask for partial WFH as part of their decision to join the company. In the end, that will drive change even if some managers object it.
