Interstate Brands makes and distributes bakery products such as Hostess, Dolly Madison, and Wonder Bread. Different distribution systems handled different products. The employer consolidated its distribution so sales representatives and distributors would handle all product lines. This meant that the union would now represent all distribution workers, rather than only some workers.
Rammage had been a Dolly Madison sales representative for 15 years before the consolidation and was not represented by the union. Now that he was represented by the union, he was put at the bottom of its seniority list, which gave preference to workers that the union had represented previously. As a result, Rammage was "endtailed" to the bottom of the distribution system, lost his regular route, and was demoted.

1. Why would the union discriminate against Rammage?
2. Why would the employer go along with the union on this issue?
