Petrobras (PBR) must maintain staffing levels of at least 80% across all its facilities in Brazil as negotiations with workers continue amid a prolonged strike, Reuters reported Sunday, citing the country's Superior Labor Court.

The ruling also prohibited unions from blocking the transportation of workers and equipment to and from Petrobras sites, including those operated by its logistics unit, Transpetro, according to the report.

Petrobras said that following nearly four months of efforts to reach an understanding at the negotiating table, 11 unions have approved the company's compensation proposal, "ending the strike movement in the vast majority of their bases," Reuters reported. There are still five dissenting groups, the news agency reported, citing the company.

Petrobras didn't immediately respond to MT Newswires' request for comment.
