You probably go to work every day expecting that you are going to be able to go home at the end of the day in the same shape that you went in. However, that may not happen. If you are in an accident at work, you may be injured enough that you have to go to a medical professional to be evaluated or treated. Theoretically, your employer is supposed to pay for that through worker's compensation insurance, but not all employers want to do that. They may try to get out of taking care of you the way that they should. If that happens, you will have to take further steps.
Contact a Mediator
One thing you can do is to contact a mediator. The mediator can talk to you and your employer as well as their worker's compensation insurance company. The mediator will get all the information from both sides and try to come up with a compromise which will work for everyone. The compromise may not make you happy, and you may not get everything that you should get, but it may be more that what you would get otherwise. One drawback to this is that, depending on your state, the agreement may not be legally binding.
Contact a Lawyer
Another option open to you is to contact a workmans compensation lawyer. There are lawyers who specialize in worker's compensation cases. They generally work on a commission basis. This means that you don't have to pay them a retainer or anything like that, they will take their fee out of any money that you may get in a settlement or judgment against the insurance company and your employer. How much that fee is depends on the state, but it is a set percentage of the settlement. Because the lawyer isn't getting paid by the hour and are just recovering their fee out of your settlement, they are going to be motivated to make sure that they get both as big a settlement as possible and as quick a resolution as possible. That is a good thing for you. The sooner everything is resolved, the faster you can get your life back on track and back to normal.
If you are in an accident at work, it can really change your life. You employer may not want to pay for your medical fees. If that happens, then you are going to need to take further steps.
