I am an employee of Walmart Inc. and had my bike stolen within the building what do I do?

Is Walmart liable for it? It was a $1500 bmx bike and if it was in fact stolen from within the building and can be verified via security camera are they obligated to pay for it? I'm worried.
Update: Where I put my bike is where other people put their bikes. It is the designated spot for them because they were getting stolen from out side of the building. This is why I as well as other employees put their bikes there also. Its a Sams' Club.
