We've just had an e-mail from our facilities manager saying that he's had a lot of dialogue with members of staff about the office being cold due to the recent cold snap.
One person has asked for the thermostat to be set to 23 in order to counter this. They are going to comply. Idiots!
If the policy is to have the temperature at 21 degrees then that is what the heating system will do. It has nothing to do with it being cold outside!
