The Miners' Union has come out swinging against One Nation, saying candidate Dale McNamara will be "tainted" by the party's "betrayal" of coal miners.

"Hunter Valley coal miners will not forget their epic betrayal at the hands of One Nation," CFMEU Northern Mining and NSW Energy District President Peter Jordan said.
"After years of pretending to be the best friend of exploited casual miners, One Nation Senators ... provided the crucial vote for stripping away their hard-won rights.
"Coal miners need political representatives who support their jobs."
