Workers at Hawaiian Cement are on their third and fourth days of the strike. Talks between managers and union negotiators broke off Saturday night. No new talks are scheduled for either group. The Teamsters International Vice President Jim Santangelo arrived this weekend to lend support to striking cement workers. Striking employees say they hope he can kick-start the stalled negotiations. Some 67 employees at Hawaiian Cement are on strike over medical co-payments and sick leave. Management wants to increase the amount workers pay toward their health insurance, at Hawaiian Cement that would be about US$95 a month. The company said the cement workers average $85,000 a year, including overtime. Striking cement workers are hoping Santangelo’s involvement will bring a quick end to the walkout. Both sides say they’re open to further negotiation.
