Houston nurses' vote on unionizing may touch Dallas

If nurses at a Tenet Healthcare Corp. hospital in Houston vote yes to a nursing union, the move would probably send reverberations across North Texas hospitals. The California Nurses Association collected enough signature cards at Tenet's hospital in the Cypress-Fairbanks suburb of Houston to force the union election. Twenty-two percent of Tenet's employees already are unionized, according to the hospital system's 2007 annual report.
