Clarify the agreement that existed
Identify the promise, policy, schedule, ownership, or shared understanding that applies before assigning blame. For a message about how to request a regular remote work arrangement, use this factual base: use recent examples, observable impact, and the work requirement rather than labels about personality.
Resolve the next dependency
State what is complete, what remains disputed, and which action would move the situation forward. Ask for a specific change, decision, or working agreement and choose a time to review it. Make the immediate next step clear enough that the recipient can answer without reconstructing the entire history.
Document without threatening
Do not diagnose, gossip, embarrass a colleague, or turn one incident into a judgment about their character. Move harassment, discrimination, threats, health risk, and retaliation into the appropriate protected process. Keep a factual record and describe only remedies you are entitled and prepared to use.
