Erin Oberson has noticed colleagues at Northern Light Eastern Maine Medical Center leaving their jobs at an accelerating clip as the COVID-19 pandemic has dragged on. The labor and delivery nurse said several have left the Bangor hospital to return to school to become nurse practitioners, while others have taken jobs in less stressful primary care offices. While much of the public’s attention has been focused on health care staff departures due to the state’s coronavirus vaccine mandate, Oberson said she knows far more colleagues who have left due to burnout than due to refusal to get vaccinated. It’s not unique to EMMC.
