What Is a Class Action Lawsuit?
A class action is a type of lawsuit that allows a large group of people with similar claims to pursue justice together in a single case. Instead of each person filing their own lawsuit, one or more individuals—known as “class representatives”—sue on behalf of everyone who was affected.
Class actions are most common when:
- A defective product injures or misleads thousands of customers
- A company engages in widespread billing fraud or deceptive advertising
- Employers violate wage and hour laws across their workforce
- Private data is stolen or misused in a large-scale security breach
These cases don’t just seek financial compensation. They hold corporations publicly accountable for systemic misconduct and can lead to changes in how businesses operate. If you’ve suffered a loss that feels small on its own but may have happened to others, reaching out to a class action lawsuit lawyer could be the most powerful path to justice.
Types of Class Actions We Handle
Our Chicago class action lawyers represent clients in a wide range of high-impact cases. These lawsuits often involve illegal or unethical conduct that affects hundreds or thousands of people in similar ways. We regularly handle class actions involving:

- False advertising and misrepresentation
- Bait-and-switch sales tactics
