It is against the law to work in conditions below 16deg.

I feel your pain.  A you know I was in a previous building for 10 months and had stiff neck and shoulders every day due to aircon circling above my head.  No one believed me until I complained and some adjustments were made.

It was only at the final stages of our company re-org when I relocated with my new team in another building, that others moved to where I was.  Believe me, now they know what it's like.

Personally I hate aircon.  It is way too cold to be sitting in those conditions every day and organistions will pay for it later on when employees become ill as a result.
