(AP) Union officials say workers of Brazil's state-run oil company Petrobras have gone on a nationwide strike protesting next week's scheduled auction of a huge offshore oil field, arguing foreign companies shouldn't be involved.
It was impossible to independently verify the immediate impact of the strike, but a National Oil Workers director named Jose Genivaldo da Silva says that at least 90 percent of Petroleo Brasileiro SA's more than 40,000 employees walked off their jobs on Thursday.
Company officials confirmed a strike but gave no information about its impact.
Workers are demanding the suspension of the upcoming auction of the Libra field under new production-sharing agreements with foreign companies that will partner with Petrobras.
Libra is believed to hold up to 12 million barrels of recoverable oil
