Rumor has it that activist Erin Brockovich is wading into the American Airlines Group Inc. (AAL) uniform issue.

The Chicago Business Journal reports that Brockovich is watching a closed Facebook group where American Airlines frontline staff are reporting problems with the new uniforms. (See also: Facebook Accused of Censorship Against Donald Trump.)

Brockovich and her team did not respond to an email request for comment from the Chicago Business Journal.

On Sept. 20, American Airlines unveiled new uniforms for its staff of over 70,000, including flight attendants, pilots and customer service crew. That day was the first time since the 2013 U.S. Airways and American Airlines merger that all staff members had access to the same uniforms.

However, almost immediately, staff complained of allergic reactions to the new uniforms, according to a Sept. 30 report by Fortune. (See also: 6 Shockingly Dangerous Jobs.)

Over 1,600 members of the Association of Professional Flight Attendants (APFA) reported illnesses from the uniforms, including rashes, headaches, hives and respiratory problems, reports the Chicago Tribune. In acknowledgement of the illnesses, APFA, which represents over 25,000 American Airlines employees, called for a total recall of the uniforms.

According to the Chicago Tribune, American Airlines responded to the demand saying that it would not be recalling the uniforms. The airline says it is working with the union and is testing the uniform fabric and packaging at an independent laboratory.
