Teacher blackout windows that do not create conference chaos

Blackouts are a product problem

When blackouts live in a sidebar comment on a Google Sheet, they are suggestions. When they live in the booking inventory, they are truth. School admins need the second one.

Rules that keep nights sane

1. Freeze blackouts 72 hours before the window opens.
2. Publish “why this block is closed” only to staff — parents just need open times.
3. Never let teachers open a personal Calendly that bypasses the school path.
4. Re-check thin rooms after blackouts land; backfill with admin-held overflow if needed.

Where software helps

SchoolConferenceGo treats blackouts as first-class schedule shape. That is how you protect lunch duty and still fill the evening for families.
