The USPS has historically placed the interests of its unions first. That hasn't changed. In March it reached a four-and-a-half-year agreement with the 250,000-member American Postal Workers Union, which represents mail clerks, drivers, mechanics, and custodians. The pact extends the no-layoff provision and provides a 3.5 percent raise for APWU members over the period of the contract, along with seven upcapped cost-of-living increases. The union is happy. "Despite the fact that the postal service is on the edge of insolvency, the union and management have reached an agreement that is a 'win-win' proposition," said APWU President Cliff Guffey on the union's website. A USPS spokeswoman said the agency agreed to the raise because it feared the decision would otherwise be made by an arbitrator who might be even more deferential to the union.
