The COVID-19 pandemic presented an array of policy problems for school districts across the country. This included balancing social distancing during in-person learning. The creation of the COVID-19 vaccine made in-person learning a more viable option again. However, the political polarization that surrounded COVID-19 extended to vaccines, with many communities experiencing hurdles in vaccinating their populace. Previous research shows how teachers’ unions influenced school district reopenings during the height of the pandemic in fall of 2020; this paper seeks to expand on this literature by looking at how teachers’ unions influence the adoption of vaccination mandates and testing. I test whether a school district has a collective bargaining agreement (CBA) with a teachers’ union, the page length of that CBA. Using an OLS regression, I find that if a teachers’ union has a CBA with its school district, the district is 33% more likely to adopt a vaccination and testing mandate than a district without a CBA. Additionally, the page length CBA has a weaker, but still significant relationship in encouraging the adoption of a vaccination and testing mandate in a school district.
