North Carolina’s transportation department allowed a racially hostile workplace but won’t have to pay damages to black workers who sued after a white co-worker hung a noose in a maintenance shop, a federal jury decided Wednesday.

Seven black workers alleged in the civil rights suit that white supervisors did nothing about the situation, even after learning of the noose. They said the rope remained on display for 35 days in 2002 beginning Feb. 1, the start of Black History Month.
