About 150 wildcat strikers at Boise Cascade's $535-million paper mill expansion project attacked a bus carrying non-union workers today, police said.
Police Chief Tom Hardy said two windows were broken with fists and a brick by shouting picketers.
Hardy said police have been escorting the buses in and out of the Boise construction site daily. The unauthorized walkout began Tuesday over the hiring of non-union labor by BE&K; Construction & Manufacturing of Birmingham, Ala., the general contractor for the project.
Boise Cascade spokesman Bob Anderson said the company has filed a complaint with the National Labor Relations Board, charging that the work stoppage is illegal and asking that the union employees be ordered back to work.
