What's the word regularly used to describe "working from home"?


I've seen a few words in a cursory search:

  * [在宅勤務]{ざいたくきんむ}
  * テレワーク
  * [在宅]{ざいたく}ワーク

but I'm interested in the situation where your usual place of work requires
commuting, but you are temporarily working from home just for the day, as
opposed to a situation where you are based primarily at home.




I asked a friend how they would ask to work from home due to say bad weather
and they said:

天候が悪く、出社困難の為、本日は在宅で仕事をさせていただいてもよろしいでしょうか？

So extrapolating from that if you were describing your own state after getting
approval to work from home I believe you would say

今日は在宅で仕事をしている。
