11 Truck drivers at a Heidelberg Materials North America ready-mix concrete batching plant in Pittsburgh, Pennsylvania, have gone on strike. The drivers’ local Teamsters union alleges unfair labour practice with regards to inward-facing driver cameras, healthcare, first-year pay, pensions and disciplinary procedures. The strike follows a second unsuccessful attempt at contract renegotiations.

Teamsters’ president Kevin Schmitt said “These drivers are responsible for all of Heidelberg Materials North America’s ready-mix operations in Allegheny County. Heidelberg Teamsters will not rest until the company returns with a contract that reflects the value of our members.”

Heidelberg Materials North America sought a court order to remove strikers from the plant entrance on 10 July 2026.
