Labor unionization efforts have resurged in the US, and union membership has been shown to improve worker conditions in some industries.To bridge this gap, the study team examined the prevalence of labor unionization among health care workers and its associations with employee pay, non-cash benefits, and work hours across the health care workforce in the United States.This nationally representative, population-based household survey allowed for a sample of over 14,000 self-identified health care workers, including physicians and dentists, advanced practitioners, nurses, therapists, and technicians and support staff.Study researchers found that labor unionization rates were low, at an overall prevalence of 13.2%, with no significant change from 2009 through 2021.Unionized workers reported earning $123 more per week than nonunionized workers, receiving better health insurance from their employer (both in terms of employer’s contribution and the kind of insurance plan), and higher chance of having a pension or other retirement benefits at work."
