Oil prices are no longer the No. 1 reason for planned layoffs in the United States this year. In May, 1,019 job cuts were attributed to oil prices, down from 20,675 a month earlier, according to a report released Thursday by global outplacement consultancy Challenger, Gray & Christmas Inc. For the year, 69,304 layoffs have been blamed on oil prices. With May's figures in place, restructuring has surpassed oil prices as the top reason for planned layoffs in 2015 at 69,698 jobs cut. "Unless there is another severe drop in the price of oil, we probably will not see another surge in oil-related job cuts this year," said John A. Challenger, chief executive officer of Challenger.
