Wal-Mart, renowned to outsiders for its elbows-out business tactics, is known internally for its bare-knuckled no-expense-spared investigations of employees who break its ironclad ethics rules. ...The investigators — whose résumés evoke Langley, Va., more than Bentonville, Ark. — serve as a rapid-response team that aggressively polices the nation’s largest private employer, enforcing Wal-Mart’s modest by-the-books culture among its army of 1.8 million employees. Wal-Mart is certainly not the only company, or even the first, to investigate its employees, a practice used widely in corporate America to guard against fraud and protect trade secrets. But despite the retailer’s folksy Arkansas image, few companies are as prickly — or unforgiving — about its employees’ wayward behavior, a legacy of its frugal founder, Sam Walton, who equated misconduct with inefficiency that would cost customers money.
No rulebreaking at Wal-Mart!
