If you are injured on the job in South Carolina, you are almost certainly entitled to compensation. However, the type of compensation you may reasonably pursue is going to depend on your employment classification. Specifically - are you an employee or an independent contractor?
Employees hurt at work are entitled to receive workers' compensation benefits through their employer's insurer. However, this is their exclusive remedy. They cannot then turn around and sue the company for personal injury damages, though there might be an option for a third-party lawsuit in certain situations. Meanwhile, an independent contractor doesn't have the option to collect workers' compensation. He or she can, however, file a personal injury lawsuit against the employer and/or general liability insurer.
There are pros and cons to each classification, depending on your circumstance. But the most important thing to remember is that just because your employer classifies you a certain way doesn't necessarily mean the courts will agree.
