If you have been denied a workers' compensation claim by your employer's insurance company, you may not be sure what to do. Medical bills pile up fast, and you're likely not earning any money as you take time off to heal. Fortunately, there may be resources available for you. Filing a workers' compensation claim may allow you to receive the lost benefits that you're entitled to. Workers' Compensation by Employer The vast majority of employers in the US are required to carry workers' compensation insurance, especially if they have more than three employees. Most companies choose to work with a large workers' compensation employer that covers employees nationwide. Some insurance companies are so large, they cover millions of employees. While you will not earn your full salary on workers' compensation, you should be entitled to a portion of what you earned before, even if you were responsible for your injury. So long as you were on company property during your shift, participating in a work-related event (such as a company outing), or injured while driving on behalf of your job, you might be eligible.
