Luckily it's always warm where I work now. The place I worked before...I was in a room with two guys who were ALWAYS hot. So I'd be sitting there with my teeth chattering, and they'd OPEN THE WINDOWS! Grr! And they told us we weren't allowed to use space heaters, not that I had one anyway.
But it's comfy at the college during the winter. It was broiling during the summer, but at least it's nice in the winter!
