# Employee Relations assignment rules

HR Service Delivery employee relations assignment rules allow you to automatically assign a group to ER cases when the assignment group is empty.

When the HR case template sets the assignment group, assignment rules are ignored.

When an ER case is created, it:

-   Checks for the Skills/Assignment group from the HR Case Template for the associated HR service. See [Configure an HR case template for an HR service](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/employee-service-management/hr-service-delivery/configure-hr-case-template.md).
-   If there is no assignment group for the HR case template, the base system provides the Employee Relations Case assignment rule.
-   The Employee Relations Case assignment rule assigns the Employee Relations group to the case.

**Note:** For more information, see [Add or modify an HR assignment rule](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/employee-service-management/hr-service-delivery/t_CreatingAnAssignmentRule.md).
