1. Go to HR Tools > HR > Settings and click + Add Rule.
2. Fill in Trigger after (hours worked, e.g. 4), Break length (minutes, e.g. 30), Compensation (Paid or Unpaid) and Requirement (Optional or Mandatory).
3. Add more rules if needed, then click Save Settings. A "Settings saved successfully." banner confirms.

Rules are saved per location. Removing a rule's row and saving deletes that rule; breaks already recorded on timecards keep their times and paid/unpaid flag.
