Sablich became a familiar personality throughout the United States during the months of November and December 1927.
The strike in Colorado was conducted by the Industrial Workers of the World; she took an active part in it, speaking out for the cause of the miners.
She wore bright red and engaged in physical fights with men (including a mine guard).
According to the Denver Morning Post, at one point Milka was offered her freedom if she promised not to attend any more meetings of the strikers.
After the massacre and Milka's release, she toured the country giving speeches to raise money for the miners.
