Sync vs Async Best Practices

If your team overlap is less than 3 hours per day, reserve synchronous meetings strictly for urgent decisions, 1-on-1s, and team social huddles. Use tools like Loom or Linear for asynchronous daily updates.

Fair Schedule Rotation

When working across extreme offsets (e.g. SF to Singapore), rotate meeting times bi-weekly so the same team member isn't always taking calls late at night or early in the morning.
