ST. LOUIS (KSDK) - Another 10 people were arrested Tuesday morning marching on Peabody Energy.
Hundreds of protestors took the streets in downtown St. Louis to protest against the company.
The protestors are trying to save their health benefits, which they could lose as part of Patriot Coal's bankruptcy filing.
While the protest was underway, an attorney representing non-union workers from Patriot Coal was successful in gaining his clients the same rights as union workers.
A total of around 20 people have been arrested at previous Peabody protests.
The next court hearing is scheduled for April.
A Peabody Energy spokesperson released the following statement in response to the UMWA's claims:
"The UMWA is fully aware that this is a matter solely between the union and Patriot Coal, and the proper process for deciding such issues is through the bankruptcy court. The UMWA retirees in question all worked for companies that are part of Patriot Coal. Peabody has lived up to its obligations and continues to do so.
"Patriot's launch only occurred after the UMWA signed off on the retiree benefit payment structure with which Patriot started as an independent company. In 2011, Patriot and the UMWA renegotiated a collective bargaining agreement and chose not to change this benefits structure.
"Patriot was highly successful following its launch more than five years ago; its market value more than quadrupled in less than a year.
"After Patriot became independent and before its bankruptcy, however, Patriot chose to make a major acquisition, went through the global financial crisis and effects of low-cost shale gas on coal demand, experienced EPA regulation that significantly raised environmental compliance costs, and saw metallurgical coal prices decline."
