Equal pay day was "celebrated" on April 4, 2017. However, it was hardly a celebration as defined in traditional terms. The day represents how many days since the beginning of the calendar year women essentially worked for free. Women of all races and across all occupations typically earn 80 cents to every one dollar that their male counterpart earns. A deeper dive into data shows that the disparity in wages is worse for African-American women (63 cents per dollar), Native American women (59 cents per dollar), and Latina women (52 cents per dollar). Teacher unions have worked hard to eliminate the wage gap; however, school administrators in Ohio are not union members, and as such, do not have the same protections against wage discrimination. This quantitative, causal-comparative study examines the relationship between gender and salary for Ohio public high school principals during the 2015-2016 school year. Additional research questions examine the impact level of education, ethnicity, and school typology have on salary in an attempt to address issues related to intersectionality. The results indicate that level of education, ethnicity, and school typology have a statistically significant impact on the salary of an Ohio public high school administrator. Specifically, the results indicate that women only represent one-fourth of the total population, the majority of women are working in the lowest paying school typology, and that future research should continue to investigate hidden factors in the existence of a real glass ceiling.
