El vals del obrero is an album by the Spanish ska punk band Ska-P, released on 21 March 1996.
The album title means "The Worker's Waltz". The album cover depicts a typical Spanish "cacique", as a symbol of capitalism, amongst other things, fat cigar in one hand and manipulating a string puppet, dressed as a worker, with the other. The breast pocket of his jacket is stuffed with banknotes. He's also wearing ostentatious gold rings, cuff-links and a gold tie pin with the eagle which symbolised Francoist Spain.
