There was an interesting round-up of Wal-Mart’s legal troubles in Arkansas-based The Morning News:

Wal-Mart has worked overtime to show its kinder, gentler side, but accusations of workplace misdeeds are surfacing in a slew of class-action lawsuits that continue to challenge the retailers new image.

There are at least 80 class-action lawsuits in 41 states pending against the Bentonville-based retailer, 76 of which stem from wage and off-the-clock issues, according to Wal-Mart’s 10K filing with the Securities and Exchange Commission.

There are more cases against the Bentonville-based retailer than those disclosed in Wal-Mart’s federal filings. Companies are not required to disclose all legal proceedings, just those that may result in "material" financial losses, or more than 10 percent of the current assets of the company.

  The paper has a table summarizing the key case.
