OPM’s recent list of Frequently Asked Questions about the agency’s massive data breach addresses the possible impact on postal workers:
Were postal worker records affected?
It’s possible that Postal employees were affected. They may be affected if they fit certain conditions.
If the Postal employees worked for a Federal agency or organization that submitted service history documentation to OPM for future retirement processing, they may have been affected. There are several reasons that these records may have been submitted. They include:
- When an individual moves from one agency or organization to another.
- When an individual separates from an organization.
- When an individual retires from an organization.
- When an organization has a change in payroll service center.
Any Postal employees that were affected will be notified either by email or by mail.
