Charter schools see as many as one in four teachers leave annually, and recent evidence attributes much of this turnover to provisions affected by collective bargaining processes and state laws such as salary, benefits, job security, and working hours. There have been many recent efforts to improve teacher voice in charter schools (Kahlenberg & Potter, 2014), including engaging in some form of collective bargaining, but we know little about the possibilities dictated by state laws. Therefore, this article describes the possibilities and variations for collective bargaining by state and for different charter types (e.g., conversion vs. newly created charters), as well as laws that have the potential to improve teacher satisfaction in charter schools. Ideally, state laws and the collective bargaining process should provide the appropriate balance between flexibility for charter school leaders, teacher voice, and protections for teachers.
