With a name like NuclearNed, I would think you'd be able to handle WAY hotter than 83.5 🙂
I had that same problem in my office last year. It was 82 degrees from 11-5 every day of the winter. It's really hard to dress for winter outside and tropical weather inside. Once it got that hot, I found it too hot to work and therefore didn't 🙂 It only gets up to 79 now. Still too hot for someone who likes it to be 69, but at least it's bearable. My office is 25 women and 3 men. I would say that 15 of the women have space heaters and run them all day every single day of the year. When they complain about it being too cold but wear skirts and sleeveless shirts, it really annoys me.
