Can I Sue My Employer?

In Washington State, when you have a workers’ compensation claim, you usually cannot also sue your employer or a co-worker for job injuries.  The L&I system replaces your ability to sue your employer for his negligence. It doesn’t matter that it’s your employer’s fault. An exception to this rule is intentional injures. If the employers’ conduct was so over the top that he intended the injury then the employer can also be sued. More information at  Can I Sue My Employer?

Another semi-exception to this rule exists for Temporary Workers. For more information see Temporary Agency Employee and Third Party Rights.

The third party election form is important. This is how you tell L&I what to do and where to go. Understand what you are doing before you complete this form. Don’t give up your right to a third party claim. Get details and a form here, Third Party Election Form.
