In Tennessee you have to prove that the condition was actually dangerous or unsafe in some way. You also have to prove that the defendant (Wal-Mart) knew or should have known of the condition(or their employees created the condition). If you can prove those two things you may have a case. My experience with Wal-Mart is that they likely have video of the incident but will not release it to you without you obtaining a lawyer or filing suit.
One of the first things you should do is see your medical doctor if you were injured. When filing a lawsuit the one of the elements you have to prove is damages. So if you have personal injuries, then get treatment as soon as possible. You should then seek out a competent personal injury attorney.
The first thing you will need is an impairment rating, then you should have an attorney review that rating to see if it is an appropriate rating for your injury. Most likely you will need an attorney, my experience is that the insurance company will not pay you full value without an attorney.
You can sue him. In Tennessee, you would want to check your policy to see if you have uninsured motorist and or collision insurance on your car. If you bring suit you would put your carrier on notice of the claim and they would be required to appear and respond.
With regard to seeing a doctor, you should do that right away, if for nothing else do it for your health. Make sure to see a good orthopedic doctor. As to your potential case against Wal-Mart, I don't necessarily agree with the other answers. Depending on the facts and circumstances surrounding your fall and the extent of knowledge you had of the condition of the floor, you may or may not have a case that you can win. Also the extent of your injury will also be an important consideration.
You should check with your licensing board to determine specifically what you are able and should do. However, if your employer takes action against you for your refusal to participate in an act that is in violation of the law or a regulation, you may fall under the Tennessee whistleblowers act. Then you may be able to file suit against your employer.
You may or may not have a civil case. However, you will almost certainly have to win your criminal case before you can be successful in a civil suit. This is something to discuss with your lawyer representing you in the criminal case.
In Tennessee you must prove two things to recover in a premisis liability case. 1) You must prove that the defendant or property owner had notice of the unsafe condition, or that they created it. 2) Next you must show that the defendant was negligent or careless in allowing the unsafe condition to exist on their property.
The fact that other employees were making those statements probably satisfies the notice requirement and if in fact those statements are true, that evidence will go along...
You should try and speak with a personal injury lawyer as soon as you can. Most personal injury attorneys , or at least our office, will agree to help you with your property damage if they are also handling your personal injury case.
Be very careful in talking with the insurance company, contrary to the slogan they are not on your side.
There are very strict laws in Tennessee as it applies to transfers of your property if you are within 60 months of entering a long term car facility. If you are able to make a transfer you may want to consider a special needs trust as well.
It would be best to consult with an estate planning attorney as soon as possible.
