A labor union’s long-running dispute against a contractor has led to a protest outside a Lawrence grocery store.

The Carpenters Union is protesting the hiring of Drywall Systems Inc. for work being done at Dillons, 1015 W. 23rd St. The dispute has been going on for more than a year, said David Wilson, assistant director of organizing for the Carpenters District Council of Kansas City.

Drywall Systems doesn’t provide an area standard wage or pay benefits for all workers and their families, Wilson said. An area standards package is based on collective bargaining with area contractors, he said.

A few protesters are sometimes seen next to the street curb in front of the store with a banner proclaiming “Shame on Dillons.” The protest will continue for the foreseeable future, Wilson said.

No one was available Wednesday to comment about the matter at the Dillon Stores corporate headquarters in Hutchinson.
