As Warrior Met emerged from the bankruptcy proceedings of the former Walter Energy, which declared bankruptcy in 2016, the new agreement with the union was negotiated. "They made the sacrifices to bring this company out of the bankruptcy of Walter Energy in 2016," Roberts said. "But today, instead of rewarding the sacrifices and work of the miners, Warrior Met is seeking even further sacrifices from them, while demonstrating perhaps some of the worst labor-management relations we've seen in this industry since the days of the company town and company store," Roberts said. Attempts to contact Warrior Met Coal for a statement were unsuccessful for some time. Warrior Met's behaviour during talks has prompted the UMWA to file unfair labour practices charges with the National Labor Relations Board.
