[Excerpt] On behalf of the AFL-CIO, I urge you to oppose provisions in S. 1789, the "21st Century Postal Act," that would create severe damage to the U.S. Postal Service ("USPS*') and its workforce. The AFL-CIO believes that the language proposed by Senators Coburn and McCain would obstruct free collective bargaining. We urge you to support efforts by Senator Mark Begich and others to modify this language so that it does not adversely affect the collective bargaining rights of the 450,000 current US Postal Service workers.
