Brazil's Petrobras hires emergency workers to keep up output in strike

BRASILIA, Feb 7 (Reuters) - Brazil state-run oil company Petroleo Brasileiro SA said on Friday that it was hiring emergency workers to guarantee operations during the

week-old strike called by unions to protest layoffs at a

money-losing fertilizer factory.

Petrobras said in a statement that it had judicial authorization to hire the emergency workers because the unions had failed to comply with a court order that they keep 90% of workforce on the job. Until Tuesday, Petrobras had said the stoppage had not affected production. (Reporting by Anthony Boadle; editing by Jonathan Oatis)
