My Dad was a Mechanical Engineer and was in charge of many large office buildings full of mainly women who were either too hot or too cold or both on any given day, or every two minutes.
He put out a memo to these workers and told them all to bring a sweater to work and hang it on the back of their desk chair. If they were COLD - put ON the sweater! If they were HOT - take OFF the sweater.
He also ended up having to lock down the thermostats, and they would still break the plastic covers over them on a regular basis and mess with the temps.
The Army never cared if I was too hot or too cold, LOL!
