I don't believe that Wal-Mart "had" to pursue this policy, I believe they routinely operate in this manner across the board as a matter of course not because they are forced to, but because they choose to and also of course because, as Prime J points out, they are legally allowed to. I find it hard to believe that treating your employees fairly automatically puts your business on the road to liquidation, or that the amount of money involved in this case or ten cases like it is anything more than a raindrop in the ocean to Wal-Mart's bottom line.
But if it didn't, it wouldn't be Wal-Mart -- it'd be Costco.
Wal-Mart's business model is to
keep the costs down -- everywhere -- and pass along the savings to its customers as lower prices. That means paying the lowest amount possible to the fewest number of employees possible, driving the hardest possible bargain with suppliers -- and, what with US tort law being what it is, acting pre-emptively when it comes to possibilities of being sued.
Costco's business model is to pay its employees decently, train them to be friendly and knowledgeable in customer service, and hire enough of them that Costco's customers feel well served -- and therefore be able to charge higher prices than Wal-Mart.
Costco's median customer earns nearly twice as much as Wal-Mart's median customer -- and Wal-Mart has a lot more customers.
The trouble is that K-Mart's business model is very much like Wal-Mart's, only it's not quite as good at it.
That means that if Wal-Mart decided *not* to pursue cost savings with absolute ruthlessness, its costs would go up and it would start to compete with Costco in a smaller market segment, with K-Mart moving into its market segment... by pursuing cost savings with absolute ruthlessness. IOW, we'd end up exactly where we started.
This particular case illustrates some of the problems with American tort law, since it provides incentives for ambulance-chasing on the one hand, and extreme pre-emptive legal action against ambulance-chasers on the other, with this highly unfortunate individual getting squashed between the two. It's an example of politically set incentives being misaligned with our interests as citizens (and, I'm fairly certain, Wal-Mart's interests as a legal fiction.)
