The United Steelworkers reached a tentative contract with Shell Oil Co. on Thursday after more than a month of contentious talks and strikes, union officials said.
The union said it had settled on a new four-year pact with Shell, the lead negotiator for the oil industry, and the U.S. subsidiary of Royal Dutch Shell in the Netherlands. The deal was reached in Houston.
The previous contract, which covered 30,000 refinery workers nationwide, expired at the end of January. On Feb. 1, the union called for work stoppages, which at last count included 6,500 workers at 15 facilities.
Thank you for the update! I was exceptionally busy this past week and missed this news.
