CREDO Action Campaign Manager Josh Nelson told CityBeat that the group emailed the petition with 4,021 signatures to the Department of Labor Wednesday morning.
The petition reads: "Requiring employees to attend a Mitt Romney political rally without pay is totally unacceptable. I urge you to conduct a thorough investigation to determine whether Murray Energy violated any federal laws on August 14th, and to hold it fully accountable if it did."
Romney appeared at the event to attack what he called President Barack Obama’s “war on coal.” He was flanked on stage by hundreds of miners with soot-stained faces.
Dozens of those miners told WWVA-AM West Virginia talk show host David Blomquist that they were pulled from the mine before their shift was over and not paid for the full day of work.
Murray Energy Chief Financial Officer Rob Moore told Blomquist on his radio show that managers “communicated to our workforce that the attendance at the Romney event was mandatory, but no one was forced to attend.”
He said that people who did not show up to the event, which organizers say drew 1,500 miners and family members, were not penalized for their absence.
“Forcing Ohio workers to participate in a political rally is unacceptable, so we're joining our friends at SEIU in calling on the U.S. Department of Labor to conduct an investigation to determine whether or not any federal laws were broken,” Nelson wrote in an email to CREDO Action’s Ohio activists on Sept. 1.
A spokeswoman for the Labor Department was not immediately able to confirm whether the department had received the petition or planned to launch an investigation.
