Brianna Pinnix was a talent acquisition specialist at Capital Rx until she was filmed giving her tongue-lashing to a group of men aboard a train bound for NYC -- and the video was posted on Reddit for everyone to see Tuesday morning.

On Thursday, a spokesperson for Capital Rx told TMZ, "Our company has a zero-tolerance policy around prejudicial or discriminatory behavior. After conducting a review of the circumstances, we acted immediately and terminated the employee in question."

The rep added, "The former employee’s actions and words are not representative of Capital Rx, and we offer our sincerest apology to those who were hurt. We are proud of our company’s diversity and will continue to foster policies for inclusion and invest in our DEI programs."

The New York Post was first to report about Pinnix's firing.

In the Reddit video, Pinnix approaches the men in their seats and starts going off on them as her companion tries to put a stop to it aboard the train.

At one point, Pinnix gets up in the grill of one of the guys and screams, 'What did you say?! Tell me what you said!" Her companion begs her to "not do this," warning that she might get arrested.

But Pinnix doesn't listen and continues to yell at the same guy, prompting him to jump up and raise his voice to her. He then sits back down, shaking his head.

After returning to her own seat, Pinnix starts sounding off about "f**king immigrants." She eventually tells the tourists, "How about you get the f**k out of our country."

The other passengers are not down with her vitriol, and they let her know it, with one woman saying, "That's messed up."
