This entire thread is as ridiculous as they come. If this is a legitimate Shayla, it should be addressed to a Rav, not a bunch of anonymous posters (me included) who may, or may not be fluent in halacha. Whatever happened to “Asay Licha Rav”?
Do people have a Rav any more? Are they waiting for a Kol Koreh on the matter? 🙂
Regarding the actual Shayla. Melacha on Chol Hamoded is generally assur unless a number of specific conditions are met. I am not a Rav or a Posek to tell anyone how their specifics work out according to halacha, however I can say this, “Melacha” has nothing to do with an office. It would be the same Melacha if done in your basement or out in the backyard. Unless of course one of the coonsiderations was doing the melacha “bitzinah”.
