ATI and United Steelworkers are still without a contract.
A tentative agreement was reached Feb. 28, just hours before the most recent contract was set to expire. But it failed to pass a union vote Monday.
ATI spokeswoman Natalie Gillespie said company leadership is disappointed the union vote was unsuccessful.
Both sides have agreed to extend the expired agreement through April 30 while negotiations continue.
Lance Jablonski, president of USW Local 1196, which represents union members at the Brackenridge Operations, was not immediately available for comment.
“In the coming days, our team will reconvene negotiating with the USW to reach an agreement that keeps ATI on the path of stability and consistency, enabling us to continue operating and rewarding our team,” Gillespie said.
The six-year deal rejected by union members would impact 1,000 workers at ATI mills and operations in Harrison; Vandergrift; Latrobe; Washington, Pa.; and Lockport, N.Y.
USW District 10 Director Bernie Hall said last month, when the tentative agreement was reached, that “this agreement is a testament to our strength and unity and makes important strides on many of our members’ top priorities, including higher wages, increased paid time off and greater retirement security.”
Terms of the contract proposal were not released by the union or the company.
ATI is among the Alle-Kiski Valley’s largest employers. In January, it reported $1.2 billion in sales for the fourth quarter of 2024. Full-year sales were $4.4 billion.
Steelworkers last staged a three-month strike in 2021, marking the first employee- driven work stoppage at the company in nearly 30 years.
