Bargaining began last week in Hilo, Hawaii, for a new Guild contract at the Tribune-Herald, with the union presenting  a three-year proposal that seeks annual pay raises, better sick leave and mileage reimbursement and other improvements. The company is offering a one-year proposal with no pay hikes and rollbacks in seniority, medical insurance and job security. On Friday, Guild members handed out flyers at a political rally in a city park with the message, "We have a long and sometimes difficult history with our management, but now we hope to begin a new relationship based on mutual respect and problem-solving."
