I'm not a fan of WFH as the default. Yes I like the option of having it, but making it my default made it really hard to create those necessary boundaries between work and home life which are mixed enough already.
Daily mindless chitchat with my deskmates sometimes yields great ideas. Being present in the office means I can just throw quips at my boss without any fuss or email drama.
My commute is 45 mins long, but is a crucial part of my day where I exercise.
Working from home was killing me, driving me insane, and creating conflict with my colleagues (some of who needed to be in the office to work, creating an underclass of sorts).
Before you ask, no I'm not a boot licker repeating company sound quotes to protect the shiny office of my boss. My workspace is small, my boss's office is a small wardrobe in the corner, all given to us by the instituion (i.e. not rented).
