Contra Costa Times: Some workers at Lawrence Livermore National Laboratory fear that the lab's ability to employ the country's top scientists, critical to its ability to carry out its mission, is in jeopardy. Under new corporate management, the workforce has been subjected to layoffs for the first time in three decades. Of the 440 employees escorted off lab property May 22 and May 23, more than 150 were scientists and engineers, including 110 with at least two decades of experience at the lab.
