NEW YORK (TheStreet) -- Walmart (WMT) is said to be discouraging workers from using a chat app created by employee and labor activist group OUR Walmart that was released on Alphabet's (GOOGL) Google Play store Monday. The app is called WorkIt and is meant to educate Walmart employees about workplace rights.

The issue Walmart is having has to do with the app's chat feature, which allows past and current employees to answer submitted questions, Fox Business' Maria Bartiromo said on "Mornings with Maria" on Wednesday.

"Do you have any concern about this app?" Bartiromo asked her guest, Forbes Media Chairman Steve Forbes.

"No, I think it's a PR black eye," Forbes answered. "You can just pass the word among the people. This is full of junk. They want to hurt you not help you. And instead you're looking like you're going against the First Amendment."

Walmart employees need to make sure they don't fall into these "PR traps," he added. "These agitators always know how to try to set you up."

Walmart told managers to warn employees that the app was not an official Walmart app and that its usage may lead to unknowingly revealing valuable personal information, the Wall Street Journal reported. 

Shares of Walmart were slightly higher in late morning trading on Wednesday.
