Hyphen needed

From a New York Times article about the ugly incident in a Philadelphia Starbucks:

The chief executive, Kevin R. Johnson, said in an interview with ABC’s “Good Morning America” that what happened to the men was “wrong,” and that he wanted to meet with them personally to apologize.

“It’s my responsibility to understand what happened and what led to that, and ensure that we fix it,” Mr. Johnson said. He said that the company was reviewing its guidelines, which can differ among its 28,000 stores worldwide, and that it would invest in unconscious bias training.

Make that unconscious-bias training. Unconscious bias training, a lifetime’s worth, is what might prompt an employee to call the police when two men of color are waiting on a friend before ordering.
