As the collective bargaining agent, the Connecticut State University American Association of University Professors (CSU-AAUP) negotiates the wages and working conditions for the full and part-time faculty, counselors, librarians, and coaches and trainers at Central (New Britain), Eastern (Willimantic), Southern (New Haven), and Western (Danbury) Connecticut State Universities. It is also a professional organization, affiliated with National AAUP, which works to advance academic freedom and shared governance in addition to other issues in higher education.

At the time of hire, faculty automatically become a member of the CSU-AAUP bargaining unit. All bargaining unit members are entitled to vote on contract ratification. However, to become an active member of the organization at no additional cost, faculty must fill out a membership form. Active members have the right to vote in chapter elections, serve on committees, and, after six months, hold office. Active members also receive discounts on insurance, academic regalia, entrance fees to certain nationwide amusement parks, car rentals, tires and tire services, legal services and much more.
