CLAXTON — Job Training Unlimited Inc., a Claxton-based company that provides job readiness services funded under the federal Workforce Investment Act in 17 Georgia counties, moved its offices this summer into a county-owned building previously used by Ogeechee Technical College. Like JTU's previous headquarters, the building is on U.S. Highway 301 in Claxton. But unlike the old location, a former hotel with limited parking south of the center of town, JTU's handsome new digs are north of the tracks and only a shade more than 10 years old.
