Maverick! : The Success Story Behind the World's Most Unusual Workplace is a business autobiography by Ricardo Semler published in 1993 by Warner Books. The book relates the management succession and increasingly unorthodox ethos of Semco, which grew to become one of Brazil's largest conglomerates. First published in Brazil in 1988 as Turning the Tables, it became the all-time best-selling nonfiction book in Brazil's history. Semler further described the unusual corporate transition in The Seven-Day Weekend: Changing the Way Work Works published in 2003.
