There's a sort of happy ending to the tragic story I linked to the other day, involving a woman who worked for Walmart, suffered brain damage in a car accident, won some money to pay for her care, and then had the money taken away by Walmart. Following the horrible PR the company got from the story, it relented and decided to let the poor woman keep her care trust fund. They explain it like this:

"Occasionally, others help us step back and look at a situation in a different way. This is one of those times," Wal-Mart Executive Vice President Pat Curran said in a letter. "We have all been moved by Ms. Shank's extraordinary situation."

How sweet. So in addition to changing the policy, they also wrote that they are "modifying their health care plan to allow 'more discretion' in individual cases." In other words, get your story on CNN and they'll be forced to back down.
Dropping this disgusting case was a good start. Now they need to change the policy completely by removing the clause from all their health care contracts. Then Congress needs to pass health care reform and ban the clause from any health care contract. Like Michael Moore's Sicko, all these stories of people screwed by the system ought to add up to something.
