Jensen v. Amgen, Inc., 105 Cal. App. 4th 1322 (2003)
Darcy Jensen, who was employed at Amgen as a module team coordinator, alleged that she sustained injuries after she was exposed to mold on Amgen’s premises. Jensen filed a lawsuit asserting causes of action for fraudulent concealment of injuries under Labor Code § 3602(b)(2), battery and unfair business practices. The trial court granted Amgen’s motion for summary adjudication of the fraudulent concealment claim, and Jensen challenged the dismissal on appeal. The Court of Appeal affirmed summary adjudication in favor of Amgen on the grounds that the company did not conceal the existence of Jensen’s injury (Jensen knew about it before Amgen did) or the connection between Jensen’s symptoms and her employment.
