Two locals of the Laborers' International Union of North America are rallying today in Carroll County against Chesapeake Energy Corp.'s use of out-of-statepipeline-construction companies.
The union locals from Canton (No. 1015) and Steubenville (No. 809) are scheduled to rally at a Chesapeake Energy well site near Carrollton from 8 a.m. to noon. About 50 union workers are slated to be on hand.
The so-called job action is aimed at Chesapeake's employment of Sunland Construction, a pipeline contractor from Louisiana.
The company is building a 3.5-mile, 8-inch pipeline.
It is the third out-of-state company hired by Chesapeake to construct pipelines, the union locals said.
The other two were from Mississippi and Texas, the union said.
