It seems like every summer when we hit the really high temperatures my ac at work goes out. I complain about it each year, but it keeps happening. When it is working correctly it is a virtual icebox in my office because of the network equipment I have in there. I'd still rather work there than from home. The only time I work from home is when I am sick or the roads are too dangerous to drive the twenty miles to work.
I like the separation of having a workplace, rather than only from home. I have the freedom to work from wherever I want though, so if I need, I will stay home - but in general, I get my ass to the office. Many people complain about their working conditions, like they are in coal mine.
I agree with all of that. My office at work is kind of my safe space.
