A Connecticut company that acquired Turbo Logistics in late October has begun exploring possible tax incentives that, if agreed upon with Georgia officials, could result in a near tripling of the work force at the company’s Gainesville operation. “We have about 150 (employees) there now. We could use our proprietary recruiting techniques and training programs to go out and hire another 250,” said Bradley Jacobs, chairman and chief executive officer of XPO Logistics.
