> Thanks to NALC and a coalition of other unions (the Rural Letter Carriers and the Mail Handlers), management associations, vendors and mailers, Congress rejected almost all the negative recommendations of President Bush’s blue-ribbon Commission on the Postal Service.

> Rep. Henry Waxman (D-CA) and Sen. Tom Carper (D-DE) were instrumental in negotiating the final details with Sen. Susan Collins (R-ME), the bill’s chief sponsor in the Senate. In an e-Activist message sent on December 9, NALC President Bill Young thanked Waxman and Carper for advocating NALC’s interests in the legislation. He also thanked Sens. Joe Lieberman (D-CT) and Daniel Akaka (D-HI), and Reps. Tom Davis (R-VA), Danny Davis (D-IL) and John McHugh (R-NY) for their roles over the years.
