Ideally, a work injury would result in you getting perfectly adequate compensation with minimal fuss. Your employer would take on the liability and move on, making sure all the while that you’re well cared for.
Unfortunately, the world doesn’t work that way. Companies do all that they can to keep their expenses down, and there could be some friction against their employees as a result. In like manner, it doesn’t do for employees to try to take full advantage of their employers, so there has to be some push-and-pull in place.
Settlement negotiations help make sure both parties are treated fairly when it comes to workers’ compensation. That said, Illinois law does favor the employee in most cases, but that only comes into play if you have adequate representation.
