To avoid being sued by the AIDS Law Project, a national security systems company has agreed to pay an undisclosed sum to a Delaware County man who said he was ousted from his managerial post soon after his co-workers learned that he was gay and that his life partner had HIV, the virus that causes AIDS.

“This settlement should send a clear message to employers that people who associate with a person living with HIV, or who are perceived as HIV-positive, are also protected by anti-discrimination laws,” AIDS Law Project senior staff attorney Ronda B. Goldfein said.
