Suddenly forcing non-remote workers to switch to remote work overnight is not going to produce great results. By the time the workers get the hang of working remotely effectively, their bosses will have already decided that it is a bad idea.
A few of my colleagues hated it and returned to their FAANG(probably for financial reasons, as well), unlike myself.
It's more different than people think.
IMO the entire way your team operates needs to be centered around them being remote. The worst is hybrid teams where they are half remote and half in office. I don't think they work well anyway you do it.
Also some people just aren't very suited for remote work, they need to be physically around their co-workers.
If you are curious about more details, the REMOTE book is a good primer on the different ways of working remotely compared to in an office. https://basecamp.com/books/remote
Your mileage may vary, but it took me half a year to be 100% while remote.
You have to reach out and communicate when you're struggling or blocked because nobody will know by your body language.
You have to step away when you need to because it's easy to get sucked into non-stop work which isn't always productive work. This is even better if you're allowed to have a truly flexible schedule (e.g. you could work a few hours in the morning, take the midday to yourself, and work the rest of your day in the late afternoon/evening or switch it up and take the morning to yourself and work the afternoon/evening).
