Notes: Strength of collective bargaining rights is based on rights accorded to miscellaneous local government workers in 2015–2019. “Banned” states are those in which miscellaneous local government workers are barred from engaging in collective bargaining. “Permitted” states are those in which local government entities may engage in collective bargaining with miscellaneous government workers but there is no statewide mandate. “Required” states are those in which local government entities are required to engage in collective bargaining with miscellaneous local government workers. Pay gap is the difference in weekly earnings of full-time local government workers ages 18–64 compared with those of their private-sector counterparts, controlling for education, age, hours worked, state, and year using regression analysis. Regression with additional demographic controls also adjusts for race, ethnicity, gender, and marital status.
