Using a Workers' Comp Lawyer
If you were seriously injured at work, you're likely owed permanent disability benefits. Calculating, negotiating, and settling a claim for permanent disability benefits is difficult to do on your own, and you'll almost always get a higher settlement if you hire a workers' comp lawyer. Workers' comp attorneys' fees are a small percentage of the benefits you win and are usually well worth it.
Or, if your claim was denied from the start, so that you haven't even been able to get paid for time off work (temporary disaiblity) or medical treatment, you should definitely consider hiring a lawyer to get your claim accepted.
