Trends in Labor Unionization among US Health Care Workers, 2009-2021

Abstract

Importance: Labor unionization efforts have resurged in the US, and union membership has been shown to improve worker conditions in some industries. However, little is known about labor unionization membership and its economic effects across the health care workforce. Objectives: To examine the prevalence of labor unionization among health care workers and its associations with pay, noncash benefits, and work hours. Design, Setting, and Participants: This cross-sectional study was conducted using data from the Current Population Survey and Annual Social and Economic Supplement from 2009 through 2021. The US nationally representative, population-based household survey allowed for a sample of 14298 self-identified health care workers (physicians and dentists, advanced practitioners, nurses, therapists, and technicians and support staff). Exposures: Self-reported membership status or coverage in a labor union. Main Outcomes and Measures: Prevalence and trend in labor unionization. Further comparisons included mean weekly pay, noncash benefits (pension or other retirement benefits; employer-sponsored, full premium-covered health insurance; and employer's contribution to the worker's health insurance plan), and work hours. Results: The 14298 respondents (81.5% women; 7.1% Asian, 12.0% Black, 8.5% Hispanic, 70.4% White individuals; mean [SD] age, 41.6 [13.4] years) included 1072 physicians and dentists, 981 advanced practitioners, 4931 nurses, 964 therapists, and 6350 technicians and support staff. After weighting, 13.2% (95% CI, 12.5% to 13.8%) of respondents reported union membership or coverage, with no significant trend from 2009 through 2021 (P =.75). Among health care workers, those who were members of a racial or ethnic minority group (Asian, Black, or Hispanic individuals compared with White individuals) and those living in metropolitan areas were more likely to report being labor unionized. Reported unionization was associated with significantly higher reported weekly earnings ($1165 vs $1042; mean difference, $123 [95% CI, $88 to $157]; P
