Charges that John L. Lewis 'saw to' the discharge of men to coerce workers. Washington, D.C., Dec. 13. Joe Ozanic, International President of the Progressive Mine Workers of America, testified before the Smith Committee investigating the National Labor Relations Board. He charged that John L. Lewis, as President of the United Mine Workers of America, caused the discharge of five men in the Progressive Union, to 'bring pressure' on other employees to leave the Progressive and join the United. 'The United Mine Workers--and if I've got to use the name of the dictator, John Lewis himself--brought pressure on the employees to force them to sign a petition. They refused. He then saw to it that the coal company discharged five men. The others then did sign the petition resigning from the Progressive Union and pledging loyalty to the United. They did it to save their jobs,' he told the committee
