As it closes and consolidates plants, defense contractor Lockheed Martin (LMT) has said it will cut more than 400 jobs in Maryland and Minnesota during the coming months. This comes as further bad news for the Baltimore area, which in 2009 added some engineering services and research and development jobs, only to lose more jobs in computer system design and related services. An average high-tech worker earned 87 percent more than an average private sector employee last year.
