The United Auto Workers saw a decline in membership and union dues last year amid restructuring and job cuts by domestic automakers. The UAW's membership through late December had declined 3.4 percent to 538,448, a reduction of more than 18,000 from a year earlier, according to its annual report to the Labor Department. Union dues, meanwhile, fell about 3 percent to $191 million in 2006, according to the report filed by the union on March 29 and recently posted to the Labor Department's Web site. In 2004, for example, dues were about $206 million, records show.
