Big Tech and Wall Street are deploying an on-demand “Uber for nursing” model that’s racking up hundreds of millions in investments while creating unsafe, high-stress conditions for nurses and patients — all to solve a nursing shortage that doesn’t really exist.

The influx of patients and lack of resources during the COVID-19 pandemic led to unprecedented levels of burnout among nurses. The subsequent rise of gig nursing platforms like CareRev, ShiftKey, and ShiftMed has been heralded as a way to bring in more nurses and provide these workers with additional flexibility.

However, amid growing public outcry over the state of the country’s health care system, a new study published by researchers at the Roosevelt Institute, a liberal think tank, found that these on-demand nursing apps can create high-risk, low-reward working conditions that endanger medical professionals and patients alike.
