Claims agents are not on your side. Their objective is to settle your case quickly and cheaply. If they can get you to divulge information that makes that easier, they will do it. The claims agent has these ulterior motives:
To act friendly and win your trust.
To make tempting offers of wage continuations or advances, which will make litigation less likely.
To direct you to railroad-approved doctors or facilities that will strengthen the railroad's case, not yours.
