Set Up a Team Communication Charter

Act as a team effectiveness coach. My team of [TEAM_SIZE] people uses [COMMUNICATION_TOOLS] and we have recurring issues with: [COMMUNICATION_PROBLEMS] (e.g. too many messages after hours, unclear ownership in group chats, email overload). Create a one-page Team Communication Charter covering: which channel to use for which type of message, response time expectations by channel and urgency level, after-hours communication norms, meeting vs async decision norms, and how to signal urgency without creating a culture of constant availability.
