The association preserves, enforces, and negotiates the certificated contract. In other words, the association ensures that faculty compensation and working conditions are protected. In contrast, the Senate concentrates on professional and teaching issues. Quite often, of course, the two organizations work together to ensure that both professional and working condition concerns are supported. On certain bodies, such as the department chair task force, representatives from both the association and the Senate work to see that department chair structures and procedures are sound educationally and create reasonable working conditions for the faculty.
