I wouldn't recommend making office visits a requirement, however, as some companies appear to do. Like all things corporate-mandated, this can seem heavy-handed and present logistical challenges for remote workers.

I believe I've seen some companies requiring quarterly travel, and this places a burden on devs with families, pets, etc.

Even then, would those who opt-out be treated differently? ("Well Jon has no problem traveling to the office, why do you?")
