This sounds like the kind of concern that you should express to your manager. It's probably much more effective for management to speak to the offenders directly than it is to convene a committee to endlessly debate a code of conduct. When presenting this to your manager, emphasize that you're concerned about the negative effects on the company (e.g., people leaving, etc.).
