Wal-Mart Watch/ Ehrenreich Lovefest Combination Post: In her second-to-last planned column for the Times, Barbara Ehrenreich takes on the invasion from Wal-Mars: It's the velocity of growth that you need to measure now: two new stores opening and $1 billion worth of U.S. real estate bought up every week; almost 600,000 American employees churned through in a year (that's at a 44 percent turnover rate). My thumbnail calculation suggests that by the year 4004, every square inch of the United States will be covered by supercenters, so that the only place for new supercenters will be on top of existing ones. Wal-Mart will be in trouble long before that, of course, because with everyone on the planet working for the company or its suppliers, hardly anyone will be able to shop there. Wal-Mart is frequently lauded for bringing consumerism to the masses, but more than half of its own "associates," as the employees are euphemistically termed, cannot afford the company's health insurance, never mind its Faded Glory jeans. With hourly wages declining throughout the economy, Wal-Mart - the nation's largest employer - is already seeing its sales go soft. In my own brief stint at the company in 2000, I worked with a woman for whom a $7 Wal-Mart polo shirt, of the kind we had been ordered to wear, was an impossible dream: It took us an hour to earn that much. Some stores encourage their employees to apply for food stamps and welfare; many take second jobs. Critics point out that Wal-Mart has consumed $1 billion in public subsidies, but that doesn't count the government expenditures required to keep its associates alive. Apparently the Wal-Martians, before landing, failed to check on the biological requirements for human life. But a creature afflicted with the appetite of a starved hyena doesn't have time for niceties. Wal-Mart is facing class-action suits for sex discrimination and nonpayment for overtime work (meaning no payment at all), as well as accusations that employees have been locked into stores overnight, unable to get help even in medical emergencies. These are the kinds of conditions we associate with third world sweatshops, and in fact Wal-Mart fails at least five out of 10 criteria set by the Worker Rights Consortium, which monitors universities' sources of logoed apparel - making it the world's largest sweatshop.
