If you followed every Democratic presidential primary debate and read the candidates’ positions on every topic and watched the AFSCME Public Service Forum held in August, you might think there is nothing left to know about the men and women vying to be the next president of the United States.

On a normal day, Sandra Pacheco, an administrative assistant in Puerto Rico’s Department of Transportation and Public Works, begins her day at 7 a.m., filing paperwork for her colleagues in the field. It’s a job that Pacheco, who is president of her local, AFSCME Local 3889, Council 95 (Servidores Públicos Unidos de Puerto Rico), does with pride and dedication.

As a public librarian for the Philadelphia Free Library, Sheila O’Steen embodies what we think of when we imagine a public service worker. Every day, she interacts with members of her community. Whether her patrons are young or old, affluent or impoverished, O’Steen shares knowledge and information with everyone she serves.
