A retired Department of Correction administrator is suing the city, claiming he was forced out of his job following a cancer diagnosis related to his service in the US Navy.

Military veteran Eric Brown claims in his Manhattan civil court suit that he was “discharged” from the correction department in 2018 following approved leave for treatment of his stage-four cancer of the lymph nodes and vocal cords.

Brown returned to work March 5, 2018, and was axed in November 2018, he says in the docs.

The 54-year-old also suffers from asthma and chronic obstructive pulmonary disease, which he’s lived with since 2013, the court papers said.

“At all times throughout his employment in DOC, Plaintiff performed duties in a highly competent and professional manner, and was never the subject of any disciplinary action taken against him by DOC,” reads the lawsuit. “Upon information and believe, Plaintiff was discharged from [his] aforesaid position of employment in DOC because of his aforesaid medical conditions of COPD, Asthma, and stage 4 cancer.”

His conditions, the suit notes, “have been determined by the United States Department of Veterans affairs to be related to Plaintiff’s military service in the United States Navy.”

The Bronx resident started at the correction department as a chaplain in 1995 and was promoted over the years to director of administrative services before his termination.

Brown claims the agency has violated the city’s Human Rights Law and is asking a judge to order the DOC to give him back his job.

He’s also requesting the city pay his legal fees and other damages.

“We will review the complaint once we are served,” a spokesman for the Law Department said.

Brown’s attorney did not return a request for comment.
