U.S. Steel is laying off more than 100 workers at its McKeesport Tubular Operations plant.

Several people called WTAE Channel 4 Action News on Friday morning and said they got layoff notices.

“As a result of business conditions, including the negative effect of the high level of tubular imports (many of which we believe to be unfairly traded), we are adjusting production at our McKeesport Tubular Operations. This adjustment in production will impact approximately 142 hourly employees,” spokeswoman Courtney Boone said in an email. “While we have made every effort to maintain employment levels at our operations, unfortunately we must now adjust our workforce to match our production levels.”
