The Seven-Day Weekend, by Ricardo Semler is a 2003 non-fiction book about changing the nature of work, with a case study of the management changes at Semler's family-owned business, Semco. It follows his popular Maverick!: The Success Story Behind the World's Most Unusual Workplace (1993). The book has been described as challenging conventional approaches to work by advocating corporate anarchy. The business principles described encourage employees to "ramble through their day or week so they will meander into new ideas and new business opportunities."
