How to set work hours roommates will respect
Tell roommates your normal work hours, recurring calls, and a few genuinely important quiet blocks. Ask for theirs. Put fixed meetings on a shared calendar and give notice for unusual deadlines.
Be specific about the request: no vacuuming during a presentation, use headphones after ten, or keep the kitchen table free until noon. Offer the same consideration in return.
Respect grows from limited, clear requests. A rule that every weekday is sacred will not last in a shared home.
