The UC Berkeley Center for Labor Research and Education has published a new report that finds many of California's private sector EMTs and Paramedics suffer from low wages and poor working conditions. Researchers from UC Berkeley and UCLA found that 22% of the State's EMS workers are employed by private ambulance companies that operate 81% of all EMS ambulances. Employee retention, turnover, effects of post-traumatic stress disorder, part-time work schedules, and inadequate training are also cited as challenges in the industry.
