"the lockdown may encourage more workplaces to embrace remote working"
It might, but I wouldn't count on it. The larger companies should have the IT chops to allow people to work from home, but will they have to will to do it is the question. I'm thinking not, because having the employees on-site is generally better from all points of view, not to mention security. Having all those people working remotely must be giving the heebee-jeebees to IT admins everywhere.
Then, of course, you have all the companies that simply can't work from home : plumbers, construction workers, supermarket employees (and stores/restaurants/bars in general), medical companies, etc. Basically, if your job is to deal with the public, you're not working from home.
Finally, you have all the consultants in various capacities. They can't work remotely because the clients want to see them there. Sure, right now I have customers allowing me to work remotely, but that's because they don't have the choice - there's work to be done and it can't wait. When the confinement is over, I've already been told in no uncertain terms that I will lose my access. Security first.
So no, I don't see that there is going to be a change in the way we work, globally speaking. Yes, some companies will realize that they can reduce their office space requirements by having people work from home but, little by little, the manager paranoia is going to creep in and the question of are they actually working is going to haunt them. And that will be the end of the experiment.
