The continued steady growth of public sector unions compels public administrators to understand the influence labor organizations exert upon local governments. The following study demonstrates the extent of union influence upon police expenditures in Florida. Union influence not only increases total police expenditures and personal services expenditures, it also causes operating expenses to rise. Union influence is less pronounced, and possibly even non-existent in capital outlays expenditures because of possible lack of interest on the part of the union in this area and also because of the existence of economically predetermined policies regarding capital outlays such as vehicle purchases. Public sector unions, by formalizing and enhancing the exit-voice phenomenon within government systems, influence the expenditures of local government. This influence manifests its presence specifically in local government expenditures. By examining the association between unionization and the level of expenditures in local government, this study attempts to illustrate the influence of unions upon local governments. Specifically, this study assesses the impact of police unionization has upon local government police department expenditures for municipalities in the state of Florida. A qualitative inquiry combines with a quantitative study to examine the extent of union influence on police expenditures in Florida.
