California Employment Class Action Lawsuits

To certify a class, the party bringing the lawsuit must produce substantial evidence of two things: ascertainability and a community of interest among class members.

Ascertainability means the class definition is clear, the estimated size is identifiable, and there is a workable method to determine who belongs. A class defined as “all non-exempt employees who worked at Defendant’s Los Angeles warehouses between 2021 and 2024” is ascertainable. A class defined as “employees who were treated unfairly” is not.

Community of interest under Sav-On encompasses four sub-elements:

• Commonality: The class members share at least one significant question of law or fact. In wage cases, a uniform policy of rounding time punches or auto-deducting meal breaks can satisfy this element across hundreds of workers.
• Typicality: The named plaintiff’s claims are typical of the class. The named plaintiff does not need to be identical to every class member, only representative enough to advance the same legal theory.
• Adequacy of representation: The named plaintiff can fairly and adequately protect class interests, and class counsel is qualified to handle the litigation.
• Numerosity: Joinder of all members individually is impracticable. There is no fixed number in the statute.

How Many People Does a California Class Action Require?

No California statute sets a minimum class size. Case law indicates that approximately 30 to 40 members generally satisfies numerosity because individual joinder at that scale becomes impracticable. Courts have certified classes considerably smaller: as few as 10 members in Bowles v. Superior Court, 44 Cal.2d 574 (1955), and 28 members in Hebbard v. Colgrove, 28 Cal.App.3d 1017, 1030 (1972). The practical takeaway is that size alone rarely defeats a class action if the other elements are present. A workplace with 35 similarly situated employees sharing the same unpaid overtime policy has a realistic numerosity argument.

Common Employer Defenses to Class Certification, and How Workers Counter Them

Most competition among employment class action practitioners happens not at the complaint stage but at the certification hearing. Understanding what employers argue, and what the response is, helps employees evaluate whether their situation is likely to survive that fight.

• Defense: “Individual issues predominate because each employee’s situation is different.”
  Employers argue that variations in manager conduct, shift schedules, or job duties make common proof impossible. The worker’s counter: under Sav-On, California courts do not require that every issue be common, only that common questions predominate. A uniform written policy of denying second meal breaks is common evidence even if employees worked different shifts.
• Defense: “The named plaintiff is not typical because their circumstances are unique.”
  Employers attack the named plaintiff’s individual characteristics to sever them from the class. The counter: typicality requires only that the named plaintiff’s claims arise from the same course of conduct and rest on the same legal theory. Minor individual differences do not defeat typicality.
• Defense: “The class is not ascertainable because records don’t exist to identify members.”
  Employers argue payroll or scheduling records are incomplete. The counter: California courts have held that the inability to identify members with precision at the certification stage does not automatically defeat ascertainability if a reasonable method of identification exists, such as cross-referencing time records with shift assignments.
• Defense: “The named plaintiff has a conflict of interest with the class.”
  Employers challenge adequacy by arguing the named plaintiff would benefit from a settlement structure that harms other members. The counter: courts scrutinize proposed settlements independently, and adequacy challenges require specific evidence of conflict, not speculation.
• Defense: “The position was reclassified or the policy was changed, making the class moot.”
  Employers claim they fixed the problem before certification. The counter: past violations remain actionable for the limitations period regardless of subsequent corrections, and class members who suffered violations during the covered period retain their claims.
• Defense: “Employees were properly classified as exempt or independent contractors.”
  This is a merits defense, not a certification defense, but employers raise it early. Under S.G. Borello & Sons, Inc. v. Department of Industrial Relations (1989) 48 Cal.3d 341, and for most post-2018 situations under Labor Code § 2775 (the ABC test), the burden is on the employer to prove independent contractor status. The existence of a shared misclassification policy across a workforce is itself evidence of commonality.
