“Northrop Grumman Information Technology Inc. has paid $429,041 in back wages to 301 mechanics, technicians and range specialists working at Fort Hood, Texas, after a U.S. Department of Labor investigation revealed violations of the McNamara-O’Hara Service Contract Act (SCA)… The investigation covering the period March 1, 2001, to Sept. 30, 2003, found the company paid $1.39 per hour for health and welfare benefits, rather than the $1.92 to $2.15 hourly rate required by the SCA. In addition, the company paid lower hourly wage rates because some workers were misclassified in the occupation.”
