Choose the right purpose for the message
Decide whether the message is meant to inform, apologize, ask, support, or close a practical loop. For a message about how to ask coworkers to limit desk interruptions, use this factual base: describe the request or behavior, its frequency, and the effect on delivery, health, or privacy.
Use detail that helps a decision
Include the smallest set of details that lets the recipient understand the impact and choose a response. Propose a workable channel, schedule, scope, or escalation route and document the agreement. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Know what the message cannot achieve
Do not retaliate, shame a colleague, or refuse essential duties without explaining the operational alternative. Use HR, a representative, occupational health, security, or legal support for harassment, discrimination, threats, or unsafe work. The message can offer clarity, but it cannot guarantee forgiveness, agreement, attention, or renewed contact.
