Assign recurring tasks to teams via delegated automation

Use a service account to reliably create and rotate team tasks in Google Workspace on a set schedule.

Who it is forInternal operations teams automating rota assignments, on-call schedules, or shared responsibilities.

The problem

Manual task scheduling is error-prone and doesn't scale when responsibilities rotate weekly or monthly. Teams miss assignments, and nobody has a central record of who is due next.

How it works

  1. Pull the up-to-date team membership from the group directory.
  2. Cycle through members to pick the next assignee(s) for the period.
  3. Create or update events in a shared team calendar under the service account.
  4. Send notifications or reminders to the assigned user(s).

What changes

Recurring assignments are generated and tracked automatically, with clear ownership and visibility in team calendars.

The trap in this one. Calendar API's eventId is not stable across deletions and re-creations, so naïvely reusing IDs for recurring events can create duplicates or orphaned entries if an earlier run failed. If a group membership change propagates slowly, the script may assign tasks to someone who has just left the team, and the automation will not retroactively reassign them without a full membership refresh.

Questions people ask

How does the script handle changes in team membership?

It queries the group live on each run, but if Workspace directory sync is delayed, assignments can lag behind reality.

Can users decline or swap assigned tasks?

Not natively; the automation writes to the calendar, but swaps need manual handling unless you build in a feedback mechanism.

Want this built?

This is a pattern we run in production. We will set up the delegation and build this on top of it — $500 per hour, most of it working the same day.
