> Write at the right time. Sharing something at 5pm may keep someone at work longer. You may have some spare time on a Sunday afternoon to write something, but putting it out there on Sunday may pull people back into work on the weekends. Early Monday morning communication may be buried by other things. There may not be a perfect time, but there’s certainly a wrong time. Keep that in mind when you hit send.
Guideline 15 states:
> Communication shouldn’t require schedule synchronization. Calendars have nothing to do with communication. Writing, rather than speaking or meeting, is independent of schedule and far more direct.
Guideline 9 states:
>"Never expect or require someone to get back to you immediately unless it’s a true emergency. The expectation of immediate response is toxic."
When you embrace asynchronous communication and you expect people to manage their own time, you should be empowered to send a note at any time because recipients should have the maturity to manage when they read. If something is truly urgent, the sender will find a way to reach you (e.g. phone), but those cases are very rare indeed so not worth having a process for.
