Have any reservist used the Escalator Principle when returning from orders?

I've been away from my civilian job for over a year and a half. I was on track to be promoted while away and the orders I got derailed that a bit.

USERRA states that we must be restored to a position you would have attained had you not been absent.

Has anybody leveraged this to be promoted upon returning to work? How do I go about navigating this?
