A strike may have been averted at the midnight hour as a tentative agreement has been reached between labor and management at Bridgestone.“We are very optimistic,” said Van Tenpenny of the United Steel Workers Local 1155. “Our negotiating committee wouldn’t have signed the tentative agreement if they didn’t think it was viable.”The tentative agreement affects the six Bridgestone plants located across the country. Saturday marked the expiration of their 2009 contract; however, both sides agreed to continue consideration of a last-minute management proposal leaving the union workers operating under an hour to hour extension of the old contract.
