Earlier this month, Mrs. Bush received a letter from representatives of nearly 600 Rite Aid employees at the company’s southwest regional distribution center in Lancaster, California documenting Rite Aid’s repeated violations of worker rights that have occurred since 2006 when workers decided to join the International Longshore and Warehouse Union (ILWU) .

Rite Aid officials agreed to settle 49 alleged federal labor violation with the National Labor Relations Board in 2008. The company is now facing a new set of alleged violations that were filed by the federal government in September, 2009. The new charges require Rite Aid officials to appear before a judge or negotiate another settlement.

“We hope Mrs. Bush will stand up for working families instead of celebrating with the corporate executives who's policies have hurt so many of us in Lancaster,” said Tim Brown, a Rite Aid employee who will attend the Tuesday evening event in New York City.
