At that time, there are employees who are working in the office who made a transition, and decided to work from their home, and most of them find themselves to be more productive, and it's better for them since they will have more time to spend with their families.
In our country, on average in one day, we spend around 2-3 hours going into the office, and going back into our homes. Just imagine that time being spent alone for travelling. For those who are going to their office who are now working from home, they find this very good since they are earning, at the same time, they have more time to do things that they aren't doing when they are working on an office.
Work from home workers tend to be less productive? I guess it depends on the environment of the freelancer/worker or whatever term you want to call. I mean I know some freelancers here in our community, and they are working pretty well, but with a silent environment that's why they are working in midnights till tomorrow morning. On the other hand, I don't know if freelancers are affected with this one, but I believe that having a noisy environment will affect your productivity. Overall, freelancers are the way to go now. No need to wear formal attire, no need to go to a meeting personally, no need to travel for 2-3 hours or even more because of traffic.
