A group of African American FDNY workers are planning to file a $150 million discrimination lawsuit against the Fire Department.

Several FDNY civil employees say they're suing to end institutional racism and wage inequality.

They are also calling for Commissioner Daniel Nigro to resign.

An administrative manager we spoke with says three of her white peers were paid up to $35,000 more than black employees.

"I'd like to see things changed, so that other employees that are coming after me, who work hard, and who like the city, and who like the fire department, and like to do good work will be adequately compensated and recognized for the work that they do," said Frances Dempsey, an FDNY Administrative Manager.

"I'm expected to perform my responsibilities with little or no expectation of promotion, supervisory opportunity, or increase in pay," said Stephanie Thomas, an FDNY Computer Specialist.

The group also says it filed a complaint with the U.S. Equal Employment Opportunity Commission in August.

In 2014, the city reached a $98 million settlement with the Vulcan Society, a black fraternal firefighter organization, who said the entrance exam was discriminatory.

In a statement, the FDNY says: "We have not seen the EEOC filing yet and, therefore, cannot respond to it directly."

It also says over the last three years, it made "unprecedented progress towards increasing and improving diversity."
