In California, you cannot sue your employer for a work injury. Instead, work injuries are covered under workers compensation.
If your work injury is caused by a third party who is not your employer, then you can sue them. For example, if you suffer an injury while working at a construction site and your injury was caused by a defective tool, then you could potentially sue the tool’s manufacturer, designer, and so forth.
This all the more reason to reach out to an experienced attorney if you suffer an injury at work. Experienced work injury lawyer Belal Hamideh can let you know definitively whether or not you have a case and, if you do, how he can help you to recover all of the compensation that you should.
