Am so glad I am a self-employed IT contractor these days because working full time in an office 7 or 8 hours a day often did my head in.
One big issue back in the day was windows (and I don't mean the operating system). On hot days some people near the windows were getting baked under direct sunlight, and wanted the windows open, with the blinds pulled too. Inevitably, people sitting on the other side of the room, in the shade, protested saying it would be too cold/too dark.
Then you had the reverse at winter time - people near the windows wanted them closed because of draughts; but people on the side of the room (where the central heating radiators were) wanted them left open slightly, to bring in cool air.
Finally, there was the use of desk fans in the summer. Some people had large fans, others quite small - both did the same job of keeping people cool, but also blowing other people's paperwork all over the shop, and some fans used to squeak when they rotated.
Lots of mutterings and gnashings of teeth as I recall. Glad that's all behind me now
