March 18 through 24, 2007, marks National Poison Prevention Week and it comes with some good news.

In the 1970s there were more than 200 child deaths a year attributed to the accidental ingestion of any manner of dangerous household chemicals, personal care products, over-the-counter medications, and cleaning agents. Due to the efforts of multiple agencies, the occurrence of these unfortunate accidents has been reduced to about 36 a year.

In 2005 about 91,000 young children visited hospital emergency rooms do to unintentional poisoning, and poison control call centers fielded more than 1 million calls. By maintaining constant availability and aggressive public awareness, organizations such as the U.S. Consumer Products Safety Commission seek to further reduce accidental poison fatalities.

To prevent these incidents, CPSC recommends the following safety steps:

I sat next to a guy named "Trent" at my first real job. He took sick days about once a week, and we all laughed about it; but secretly resented him for taking advantage of the rest of us working stiffs, who actually worked every day. And dared not to take sick days for fear our bosses would think badly of us; that we were lazy, or hypochondriacs, or unhealthy.

Wal-Mart Stores, Inc. (NYSE:WMT) is cracking down on the Trents in its workforce, according to the Wall Street Journal this morning [subscription required]. The company has enacted a new attendance policy. Now, if you have the sniffles, or chronic back pain, or a hangover, or mono, you have to call an 800-number; obtain a code; and give that code to your manager. The system will track sick time and whether or not your absence is authorized; those employees who get too many unauthorized absences will be terminated.

Even more ominous, employees with too many sick days will be encouraged to apply for an unpaid leave of absence. Critics naturally are attacking Wal-Mart from every direction, wondering if the company is trying to shuck the unhealthy workers from its roles. Whether or not this is true, it's certainly an icky process for Wal-Mart to enact, and seems a bad move for a company already under fire for overworking its employees.
