Representatives of the NALC will have the honor of laying a wreath at the Tomb of the Unknown Soldier at Arlington National Cemetery in Virginia.

All NALC members, their families and friends are invited to observe the event.

It will be held on Wednesday, Oct. 7, directly following the noon changing-of-the-guard ceremony.

The Tomb of the Unknown Soldier is a monument dedicated to U.S. service members who have died but whose remains are unidentified. Traditionally, presidents and other dignitaries have laid wreaths there as a way of honoring the country’s military veterans.

The Postal Service is the largest civilian employer of veterans. Currently, 120,000 postal workers—21 percent of USPS’ workforce—are veterans.
