A black employee at Boeing has filed a federal lawsuit against the plane manufacturer alleging racial discrimination after he said he found a noose hanging near his desk and signs near his workspace bearing the N-word, according to reports.
Curtis Anthony, a quality inspector on the 787 Dreamliner at the plant in North Charleston, SC, alleged that unidentified white co-workers have repeatedly used the racial epithet in his presence and also urinated on his desk several times beginning in April 2017,
the Post and Courier reported.

TOLEDO, Ohio (AP) — Workers who sued General Motors after nooses and racist graffiti were found at its largest U.S. transmission plant nearly two years ago are still facing racial harassment, their attorney said Thursday.
Just this week, one of the workers found a monkey doll and a racist drawing near his work station, said attorney Michelle Vocht.
The harassment has been ramping up since December — including threatening and racist messages left on restroom and factory walls and near machines where the employees work — after workers began speaking out publicly, she said.
Nine workers sued GM last April, saying the company didn’t do enough to stop racial harassment that stretched over four years and included the discovery of five nooses in the spring of 2017.
