Are these collective bargaining efforts more effective when unions operate on behalf of a broader constituency, or are outcomes better when unions concentrate on narrower interest groups? This study focused on part‐time instructional faculty at four‐year institutions in the U.S. and considered four employment outcomes that may be influenced by different types of union representation in collective bargaining agreements with their academic employers: pay for courses taught, health and retirement benefits, and contract length for teaching. Union membership criteria and coalition operating strategy are both found to significantly influence these outcomes, with higher course pay, greater odds for health and retirement benefits, and longer contract terms generally associated with unions that include all types of faculty as members, rather than representing part‐time instructors separately from others, and that choose to ally with other unions in their efforts, rather than operate alone.en
