Lol..they do

I was the one of three non-Jews at a corp. in Columbus Ohio, and trust me, some of those days are regarded as high religion days, where they are not even supposed to be on the phone.
I had a key, so I basically manned our office on those days. It was funny how they would call in ask for the $$#'s and tell me not to tell anyone else they had called in. I was not permitted to contact any of them on these days.
I always thought it funny how offices were shut down on Christmas day tho

You would think they would just work thru it.
