Over the past year, demand for healthcare workers has quietly propped up the labor market as other sectors reined in hiring or even shed jobs. On Wednesday, the full power of healthcare's role burst into full view, and marked a clear shift in a labor market now geared toward the hard, often physical, work of caring for America's aging population. Nearly all of the 130,000 new jobs added in January were healthcare jobs or positions related to healthcare. The construction and manufacturing sectors also took on new workers, while employers cut jobs in government, finance, information and transportation and warehousing. Healthcare is "way outperforming most of the rest of the economy," said Laura Ullrich, director of economic research at jobs website Indeed.
