A union representing around 200 Norwegian oil workers has announced that workers intend to strike on June 4 if an agreement is not reached with management. A strike would stop halt production at two of seven offshore fields, at least. In accordance with Norway’s labor laws, a mediator is scheduled to work with the union and management and has set a deadline for negotiations. Norway is the largest oil producer in Western Europe, this strike would lead to significant losses if it were to occur.
