This is an important point. The transition to working from home is not "Here is a laptop with network access, try to ignore the pandemic, go", that is a recipe for a bad experience. Like wise, working from an office completely sucks if it is "Here is your cubical and desktop with network access, try to ignore the pandemic, go".
There are real traps when it comes to WFH that need to be considered, even outside COVID. Trying to work from the couch or bed is 'possible' but 99/100 a terrible idea. You will likely need a fairly dedicated space, setup that supports your workflows. These things take time to workout, and having a supportive company that gets this can make such a difference.
Once I found what works for me and was clear about what I expected from employers, things were generally a lot better. Saying that, if your bosses ever become heavily anti-WFH, they can make things suck pretty quickly, but the same bad office politics/dynamics I guess.
