Re: Thermostat located in your office
It has come to our attention that the thermostat located in your office is frequently being turned off. Please be aware that although this thermostat is located in your office, it actually controls the temperature on the entire second floor. When it is turned off, it affects not only your office, but all the surrounding offices as well. We ask that you not touch the thermostat. The other second floor tenants are complaining about the lack of heat in their offices.
If you wish to adjust the temperature in your office at any time, please speak with me or with one of my assistants. We would be happy to help you create an environment that is comfortable for you and your office staff, but please remember that we need to consider the comfort of everyone in the building. Thank you for your cooperation.
