Based upon actual union organizing in the 2000 Los Angeles janitors' strike, this picture book with text in Spanish and English features young Carlitos, a child who helps his mother become a leader in the strike. With support from his teacher, Carlitos and his school friends make protest signs, with Carlitos' sign saying "I love my mama. She is a janitor."

¡Sí, Se Puede! / Yes, We Can! is a bilingual fictional story set against the backdrop of the successful janitors' strike in Los Angeles in 2000. It tells about Carlitos, whose mother is a janitor. Every night, he sleeps while his mother cleans in one of the skyscrapers in downtown L.A. When she comes home, she waves Carlitos off to school before she goes to sleep. One night, his mamá explains that she can't make enough money to support him and his abuelita the way they need unless she makes more money as a janitor. She and the other janitors have decided to go on strike.

How will Carlitos support his mother? Carlitos wants to help but he cannot think of a way until his teacher, Miss Lopez, explains in class how her own grandfather had fought for better wages for farmworkers when he first came to the United States. He and the other children in his class join the marchers with a very special sign for his mom!

¡Sí, Se Puede! is a Jane Addams Peace Award Honor Book, a Skipping Stones Honor Book, as well as a selection for The Best of Beyond Difference, a recommended list of the top 10 diversity books published in 2002.
