This directory provides the 1990 collective bargaining results and union activity for higher education in the United States and Canada. Sections include lists of: (1) U.S. faculty contracts and bargaining agents; (2) U.S. adjunct faculty contracts and bargaining agents; (3) U.S. graduate and teaching assistant contracts and bargaining agents in public and private institutions; (4) information on faculty collective bargaining at Canadian universities; and (5) a summary of U.S. agent elections for 1990. Eighteen tables and charts (over 50% of the publication) present the following statistical data: recognized faculty bargaining agents and contracts for various higher education institutions, both private and public, from 1974 through 1991; the various distributions of faculty unionization by campus and bargaining agents; a summary of decertifications; and the status of public sector collective bargaining legislation. Also included are lists of the bargaining agents cited in the directory and the non-faculty bargaining units that were deleted from the main body of the directory. "No-agent" votes from 1971-1990 are also listed. An index is provided of U.S. and Canadian institutions cited in the 1991 directory. (GLR)
