This article discusses the creation and promise of the American Federation of Teachers (AFT) resolution "¡Si Se Puede!: Improving Outcomes for Latino Children and Youth and Addressing the Needs of the Latino Community." The resolution affirms the AFT's commitment to elevating the importance of Latino issues. As a union committed to social justice and equality of educational opportunity, the AFT is advancing the credo that supporting Latino children and families is union work. In addition, the author describes her own immigrant experience and how it informed her work with English Language Learners and their families. She presents Tara J. Yosso's six forms of "community cultural capital," which all help to shape Latino youth. In advocacy work for ELLs, the author says it is always important to emphasize that this population is not monolithic. The professional educator's role is to recognize the diversity of ELLs and continually ask, "Are we meeting the diverse needs of this heterogeneous population?" As the promise of "¡Si Se Puede!" begins to become a long-hoped-for reality, remember that at the very heart of the union movement is the belief that we don't achieve anything in this world alone. We work together, in solidarity--and that always has been, and always will be, our strength. We live our history, and our union principles, in our daily actions. And that's why the author is proud to say, and why our union has said, supporting Latino children and families is union work.
