According to a New York Times report, black employees at the U.S. Mint say they feel threatened and marginalized.

The report states Black employees at the mint say the agency has a culture of racist behavior and feel a “lack of psychological safety,” describing a workplace full of biases and microaggressions.

However, the agency has had issues with employees and race in the past. In 2017, a white employee was placed on leave after using rope from coin bags to make a noose and placing it on a Black employee’s chair. The employee challenged his removal, and the mint later agreed to a settlement with the worker.

CNBC also reported at the height of the Black Lives Matter movement, Black employees at the U.S. Mint sent a letter to former Treasury Secretary Steven Mnuchin detailing several racist incidents, including the N-word written in restrooms and more nooses.
