Federal workers wearing masks depicting Brazil's President Dilma Rousseff fake a fight with an indigenous man during a protest against the new policies for the demarcation of indigenous lands in Brasilia July 26, 2012. Brazil's civil servants haven't gotten President Dilma Rousseff's message. A slowing economy, dwindling tax revenue and falling demand for the country's commodity exports mean the government must tighten its belt, she argues. But customs workers, university professors and myriad other federal employees are staging strikes across the country, pushing for salary increases worth 92 billion reais ($45.3 billion). The signs read, "against the embarrassing 'Porcaria' 303"(L) and "here rest the indigenous rights"(C). REUTERS/Cadu Gomes (BRAZIL - Tags: CIVIL UNREST POLITICS)
