Some 74 members of Norway's Lederne oil and gas labor union plan to go on strike from June 12 onwards if state-brokered mediation with employers fail, and would likely force a reduction of oil output, the trade union said on Friday.
Gas production should remain unaffected however, Lederne union chief Audun Ingvartsen told Reuters.
A strike would affect senior personnel at the Gudrun, Oseberg South, and Oseberg East platforms, all operated by Equinor, he said.
