According to a Worker Adjustment & Retraining Notification dated July 18, the U.S. energy major laid off the employees when its takeover of Hess was officially completed. The merger was delayed for over a year but even as the green light for it was awaited, Chevron had been making preparations so it could close the deal with Hess quickly, Reuters previously reported. Information technology workers from Chevron and Hess met regularly to plan the integration, and Hess employees were informed that they could request a severance package following the deal's close.
