Brazil's embattled oil company Petrobras said it will launch a voluntary layoff program to cut an estimated 12,000 jobs in a bid to save up to 33 billion reais ($9.20 billion) by 2020. The program will cost 4.4 billion reais and is open to all employees, according to a statement from Petrobras, which has been hard hit by low oil prices, refinery project problems and a massive price-fixing, bribery and political kickback scandal.
