Update on-call group with scheduled member every hour

Your on-call schedule updates don't reach chat groups, causing missed pages and slow incident responses. Keep the chat on-call group aligned so responders see the right owner within minutes.

Overview

When chat membership lags behind the canonical on-call roster, pages go to the wrong person and incident triage slows. Keep the chat on‑call group aligned with your schedule so responders see the correct owner within minutes and handoffs are cleaner.
