For both proponents and critics alike, among the most salient features of charter schooling today is their freedom from collective bargaining agreements that shape staffing and work rules and limit school administrators' discretion. This is changing in some states where a small but growing number of charter schools are unionized. How collective bargaining agreements forged by charter school teachers and administrators shape the freedoms charter schools traditionally enjoy, and whether these differ from traditional school districts, is important to understand unionization's impact on the sector. We analyze and compare collective bargaining agreements in unionized charter schools with those found in nearby, traditional school districts. The results suggest that CBAs in charter schools are similar to those in school districts, but may also preserve administrator flexibility in areas related to managing teacher talent.
