A plan to provide up to $20 million in city financing for Milwaukee Tool's new downtown office, which could have up to 2,000 employees, received its first public approval Thursday. But that was only after a labor organization raised concerns about the lack of a community benefits agreement on wages, benefits and working conditions for janitors and other employees of outside vendors at the future office. The Redevelopment Authority board unanimously recommended approval for the financing plan, which also needs Common Council approval. But those same concerns likely will surface at the proposal's next public hearing. That could be at the council's Zoning, Neighborhoods and Development Committee on April 27.
