The legality of an employer's actions in this situation can vary depending on whether they have workers' compensation insurance and the specific circumstances of your case. If your employer doesn't have workers' comp insurance and you're considering a negligence claim, the situation becomes more complex. It's crucial to speak with a qualified work injury lawyer to understand your specific rights and options. An attorney can assess your unique situation, explain the potential consequences of filing a claim, and help you make an informed decision about how to proceed.
