Effective immediately, PS Form 1188, Cancellation of Organization Dues From Payroll Withholding, is revised to reflect a change of address for the National League of Postmasters. The March 2007 edition of this form replaces the July 2002 edition. All previous editions of PS Form 1188 are obsolete and must be discarded/recycled. PS Form 1188 is available on the Postal Service™ Intranet and upon request from the Human Resources Shared Services Center (HRSSC). The form has been reformatted for ease of use, and it can be completed online.
