California Wage and Hour Litigations In August 2014, Ms. Holzer filed a complaint in the Central District of California (Holzer v. DCH Auto Group (USA) Inc., Case No. BC558869) alleging that her employer, an affiliate of DCH Auto Group (USA) Inc., failed to provide vehicle finance and sales persons, service advisors, and other clerical and hourly workers accurate and complete wage statements; and statutory meal and rest periods. The complaint also alleges that the employer failed to pay these employees for off-the-clock time worked; and wages due at termination. The plaintiffs also seek attorney fees and costs.

The plaintiffs (and several other employees in separate actions) are seeking relief under California’s PAGA provisions. During the pendency of Holzer, related cases were filed that made substantially similar non-technician claims. DCH and all non-technician claimants settled their individual claims in mediation in 2017. In January 2017, DCH and all non-technician plaintiffs agreed in principle to settle the representative claims, although this settlement has not yet been approved by the California courts as expressly contemplated by the parties and required by applicable law as a condition of the agreed release of claims.
