ddw,

Alarm bells ringing. Be careful of passing the buck to managers/supervisors without having tried to discuss it first with the alleged perpetrators. If you and your colleagues have not politely requested the two people to be more aware of the needs of others in the office, and you jump straight to the part where you put it in a letter then you are risking a huge backlash, with cries of harassment, etc.

Putting a complaint in writing without making even a token gesture of negotiating with the people concerned will just make them see red. Written complaints can make people very defensive and often scared because of fear of having the document placed on their personnel files and used later as ammunition in various situations. Scared, defensive people can often fight back very aggressively.

Be seen to be doing things in the right way. "Being seen" is the key to this. Don't leave yourself open to backlashes if you can help it. Do everything by the book and don't give them any ammunition.
