A court has inherent authority to ensure that PAGA claims can be fairly and efficiently tried and, if necessary, may strike claims that cannot be rendered manageable. As a matter of due process, defendants are entitled to a fair opportunity to litigate available affirmative defenses, and a court’s manageability assessment should account for them. Here, the PAGA claim was based on the alleged misclassification of Staples store general managers as exempt from wage and hour regulations. Staples alleged that individual store general managers spent more than 50% of their time on executive tasks and therefore were exempt. Tasks varied by store, so proof would be individual. Plaintiff refused to provide the trial court with a trial plan to show how the case could be managed. The court did not err in striking the PAGA claim under these circumstances.
