WAUSAU, Wis. (WHBL-WSAU) - A Massachusetts tech firm will add 200 jobs in Wausau over the next three years. Collaborative Consulting says it will build an onshore software development and support center in central Wisconsin. Governor Scott Walker says the state gave more than 2-million dollars in tax credits and job training credits to make the deal happen. The city has been working on the deal since June and will offer incentives for employees who buy or lease homes in Wausau. The company will scout a location for its new facility next week and hold a two-day hiring blitz at the local technical college.
