OAKLAND — The employment contracts case against Lawrence Livermore National Security LLC was sent to a jury on Wednesday afternoon following a six-week trial that put the nuclear weapons lab’s 2008 post-privatization layoffs in focus.

Though the testimony was complicated — ranging from psychological tests to dream interpretation to economic statistics — jurors in Andrews v. Lawrence Livermore National Security are tasked with answering a seemingly simple question: Was the lab unreasonable, discriminatory or arbitrary when it laid off five longtime employees? That’s the standard plaintiffs have to meet to establish that the workers’ "reasonable cause" employment contracts were breached.
