About 1,800 Indianapolis-area AT&T workers could go on strike if they don’t reach a deal with the company soon. Their contract expired Sunday morning, but they showed up for work today. The union is trying to keep AT&T from raising health care insurance premiums. AT&T said it is paying 92 percent of the health care costs for employees and wants workers to start paying more. Fox 59 will have more at 10 p.m.
