Wal-Mart, along with other companies that are not unionized, is being condemned by a lot of people. For these people, getting involved in a union is a big thing, but actually, when companies are paying good money to their workers, unions are not necessary at all. Sam Walton and Henry Ford did this, and they were rewarded. Fed Ex is doing the same thing and is also being rewarded by the free market.

For Wal-Mart, indeed, it's not necessary to have a union. If its workers don’t like working there anymore, they will just have to quit, then. Re-training them can prove more costly. Health insurance, too, is expensive, and with all the problems the US is facing in its health and medical industry, so why would Wal-Mart risk all these?
What people don’t understand is that with the reduced prescription costs, Wal-Mart is actually saving billions of dollars every month for consumers. It is in a way helping solve the problem and not causing a bigger problem. Wal-Mart deserves to be recognized for this.

As you can see, Unions do not change the world; they cannot make a country great. It’s often the free market that can do this kind of thing.
