Last year (18), the Oscar-winning actress began a boycott against streaming giant Netflix for allegedly failing to offer her a fair salary for a comedy special.
Mo'Nique, 51, then appeared on U.S. talk show "The View" to discuss it with the hosts, including Whoopi, who told her that she would have given her advice on what to expect from pay negotiations.
"I said if you had called me I could've schooled you on what was expected," the "Ghost" star told Mo'Nique.
However, the "Precious" star was stunned by Whoopi's comments, and recently told Vulture that she was disappointed with the Oscar-winning icon.
"When you have a woman saying, 'I could have schooled you,' someone would say, 'What was the schooling going to be?' When I look at this woman you say is our icon and our legend – she is," she fired.
"But, how many things has Whoopi Goldberg executive produced? Whoopi Goldberg has always been the help, and I say that humbly. So what is it that you're going to school me on? I've been doing it for almost 30 years," Mo'Nique added.
The actress and comedian, real name Monique Hicks, claimed she only had three minutes to talk about inequality in Hollywood during her appearance on the talk show, and slammed Whoopi for allegedly overlooking racism.
"This is a woman who says 'I could have schooled you,' and this is a woman who accepted Ted Danson in blackface, and our community praises this woman," Mo'Nique added.
"So oftentimes, we do it to ourselves. But, I just can't. Understand, I love my sister. However, when you know you're being fed the wrong food, you must say, 'I can't chew this, y'all'," she added.
