A black security officer at a Wisconsin high school has been fired for telling a student who is also black to stop calling him the N-word.

The firing of Marlon Anderson from West high school in Madison prompted some students to come out in protest Friday morning and for school officials to say they would review policies on the use of racial slurs in schools.

Anderson told NBC News on Friday that after a black student repeatedly called him n – – – – -, he asked the student last week to stop.

This week, Anderson said he learned that school officials had terminated his work, citing a zero-tolerance policy regarding the use of derogatory language by employees.

“My understanding of the policy was white staff should not use the N-word under any circumstances,” Anderson said. “But I had no idea I was being called a word, and I tell the student not to call me a word will get me fired.”

Anderson said he worked at Madison Metropolitan school district for 11 years and at West high school for 3 years.

Anderson shared the news of his firing in a Facebook post Wednesday.

“Short story. … I get called a b – – – – ass n – – – – student, I replied ” don’t call me n – – – -!”And I was fired,” he wrote, adding that the district’s response surprised him.

Madison Teachers Incorporated, the Union that represents teachers and support staff, said it filed a complaint Thursday seeking Anderson’s reinstatement with full pay back.

High school students held a walkout Friday morning in support of Anderson and marched to the district’s administration building. Videos posted on social media showed teachers at the school also joining the departure.

Anderson’s son, Noah, 17, who is President of the black student Union, helped lead the protest.

The school Board President said officials will review the district’s policy.

“We have taken a tough stance on racial slurs, and we believe that language has no place in schools,” Board Chairwoman Gloria Reyes said in a statement.

The Board will review its “core policies and address them through a racial justice lens, realizing that universal policies can often deepen inequality,” the statement said. “We will interview the community for help in this process.”

County superintendent Jane Belmore told NBC News in a statement Friday that after the incident occurred, “different perspectives from many aspects of our community are surfacing.”

Let me be clear, there is no doubt that language issues and racial slurs are harmful, ” Belmore said. “However, at this stage we have the opportunity to look more deeply into the response to the use of racist abuse in our schools.”

The superintendent added that the district would act as quickly as possible on the appeals process for Anderson.

Anderson’s Facebook post drew hundreds of comments of support, including from some who said they were former students and that Anderson helped them feel safe.

Anderson said the response on social media and from the community has been overwhelming.

“It gets me a little emotional because, honestly, you don’t get that kind of response from people until you’re in the box,” he said Friday. “But I had the opportunity to hear the impact Ive had on people’s lives.”
