An amendment to prohibit employers from hiring or threatening to hire permanent replacement workers during the first eight weeks of a strike over economic issues. The amendment provides that an employer would be free to hire permanent replacements for economic strikers once a strike had lasted more than eight weeks. The amendment also extends the period during which permanently replaced workers could vote in union representation elections from the 12 months permitted under current law to 18 months, requires that unions take strike votes by secret ballot, and restates current law by declaring that an employer would not be required to reinstate striking employees who have engaged in violence. The substitute also expresses the sense of Congress that the NLRB should give top priority to adjudicating cases involving the reinstatement rights of permanently replaced workers; that the President should establish a commission to recommend statutory changes in the procedures for filling NLRB vacancies and changes in the number of NLRB members, other changes in operating procedures and in funding levels to expedite the board's consideration of cases, and changes in the National Labor Relations Act that will provide expedited relief for certain complaints and actions.
