As the fall TV season approaches, the ultimate worth of Houston Medical remains under debate. But one thing is certain: The media has picked up on our Med Center excellence. Case in point: Fortune magazine, that bastion of biz lists, heralded St. Luke's Episcopal Health System as one of the nation's top 100 places to work. The chronicle of commerce cited St. Luke's generous benefits and compensation (the starting salary for a day nurse is $42,636) and a "commitment to teamwork." Rather than a cheap "cake and ice cream day," St. Luke's throws an employee appreciation week, featuring massages, karaoke contests and snazzy polo shirts. The hospital system even threw a "Fun Fest" for employees when it was named to Fortune's list. But it is perhaps the staff's performance during Tropical Storm Allison, when nurses waded through waist-deep water to salvage food for patients, and staff formed "human chains" to funnel medical supplies through 25 flights of stairwells, that admitted St. Luke's to the winner's circle.
