Around 15,000 employees in hospitals around Minnesota and Wisconsin began the largest private sector nurses' strike in US history on Monday, calling for improved working conditions and higher pay.
Employees in the United States have reported being worn out from working during the Covid-19, and strikes have been frequent over the past year.
A representative for the Minnesota Nurses Association, which was organizing the action, stated that the three-day nurses' strike would continue until Thursday morning.
Despite potential interruptions, hospitals have planned to continue delivering care.
An organization that claims to speak for the hospitals has suggested three years of pay hikes of between 10 and 12 percent. The nurses are asking for raises of between 27 and 30 percent.
According to the hospitals, "all those who work in healthcare must adapt to how we serve people in light of the continual transformation in healthcare."
