When you got hurt at work, you were frustrated. You always followed the rules, but a new worker made a mistake that resulted in an accident. Now, you're faced with something even worse: the denial of your workers' compensation claim.
As someone who has been working for your employer for many years, the last thing you expected when you got hurt was that your workers' compensation claim would be denied. You were in the heart of the action, working on a long-term project for your employer. There's no reason for a denial, in your opinion.
