12:24 PM PT -- Mayweather Fitness co-founder and CEO, James Williams, one of the people who the letter was sent to, tells TMZ Sports the following ... "My team and I have consistently operated Mayweather Fitness with integrity and in full compliance with all applicable laws and regulations, and we look forward to that being clearly reflected through current proceedings."

"I’ve always had a great relationship with Floyd, and want to make clear that the letter is correct in stating that I oversee and am responsible for all operational aspects of the business. Floyd is not involved in the day-to-day operations."

"My focus remains on leading the company, supporting our partners, and continuing to build the brand."

TMZ Sports obtained a letter, sent last week by TBE's attorneys, demanding that the franchised health clubs fix a laundry list of alleged issues, or they'll find themselves in court opposite Floyd.

Among the 50-0 fighter's beefs, Floyd says Mayweather Fitness + Boxing, with over 50 locations in the U.S., has allegedly failed to pay their employees wages, and the legendary boxer, who says he has no control over day-to-day operations, is paying the price.

"Mr. Mayweather has not participated in the management, operations, or strategic oversight of [Mayweather Fitness]. Despite his limited involvement as a brand ambassador, your organizations have continually and improperly exploited his name, image, and likeness for financial gain while simultaneously embroiling him in lawsuits and negative press."
