[Excerpt] It is unlikely that any technical and professional employees will be organized in non-union high tech firms until more blue-collar production workers become union members. There are, however, some high technology companies which already have heavily unionized blue-collar workforces. Two industrial unions have recently tried to recruit new members among the engineering and computer personnel at such firms. The experiences of the Communications Workers of America (CWA) at AT&T Technologies and the International Union of Electronic, Electrical, Technical, Salaried, & Machine Workers (IUE) at Raytheon indicate that the obstacles facing unions in this type of "high tech organizing" are formidable.
