Employees at Brazilian state-controlled oil company Petroleo Brasileiro SA working at Campos Basin, the largest oil-producing area in the country, approved a strike to begin Friday, an oil workers union said.
The Campos Basin produces around 60 percent of Brazilian oil. The employees rejected a proposal by Petrobras, as the company is known, of a 6 percent rise in wages. The union questions proposed changes to its contracts that would
allow Petrobras to reduce the number of hours worked.
Petrobras did not respond immediately to a request for comment.
