Working in a SCIF is the WORST. Never again. Though I was able to work in one, very briefly, that had windows. It was bizarre to me being in a SCIF but with windows that had blinds open...
Working in a SCIF isn't so bad when you've got an outside office. I typically spend half my day in each location. I have had days, however, where I go into the SCIF in the morning and don't emerge until its time to go home. Fortunately, that's pretty rare.
I worked at a place that put a cube farm in a 'cleaned' out oil bunker for the former power plant. They built false walls and had airflow between the concrete wall and the false wall[1] which was a rather scary wind noise since we were 50' underground. Obviously no natural light and cell phones and radios didn't work. Had to wear a tie / jacket because dress codes even though it would have been illegal for a client to get into our area. I call that job my "3 Seasons in Heck".
1) something to do with concrete still bleeding oil even if sealed so smell wouldn't get to us.
And for those wondering what is a SCIF: "A Sensitive Compartmented Information Facility (SCIF; pronounced "skiff") in United States military, security and intelligence parlance, is an enclosed area within a building that is used to process Sensitive Compartmented Information (SCI) types of classified information."
