"We have zero tolerance:" Illinois zoo officials investigating employee’s controversial photo

BROOKFIELD, Ill. -- A zoo in Illinois is investigating a controversial photo that some are calling "racist."

The photo shows a woman wearing a Brookfield Zoo uniform with the caption:

"At work serving these rude (expletive) white people."

The photo sparked outrage from some customers and was shared thousands of times of social media.

Zoo officials confirmed the woman is an employee. They said in a statement:

"Yesterday, we became aware of the actions of a single employee which we agree are unacceptable. This employee's statements in social media are in violation of our policies and do not reflect our institution's values. We have zero tolerance for these kinds of divisive behaviors. We treat all employment matters confidentially, but rest assured that we have taken prompt action to remedy the situation."
