Brazil's unemployment rate from September to November reached a record high of 11.9 percent, the country's statistics agency IBGE said.
IBGE said the rate means that 12.1 million people were unemployed during that period, up 33.1 per cent from last year.
The employed population fell by 2.1 per cent to 90.2 million. The number of people employed in the private sector with a formal contract fell by 3.7 per cent to 34.1 million.
According to the IBGE, unemployment rose particularly of crucial sectors, such as agriculture, industry, financial services, construction and real estate.
Brazil has been slogging two years of recession, and the unemployment rate is only one of several indicators which reflect the country's poor economic performance.
Despite rising inflation in the past year, Brazilian workers average monthly wage remained stable at 2,032 reais ($619).
