Five hundred ambulance workers have joined picket lines across Yorkshire and North Lincolnshire for a 12 hour walk out.
Members of the Unite Union are taking action because they say the Yorkshire Ambulance Service NHS Trust are risking patient safety, by allowing new emergency care assistants to work with paramedics after only six weeks training.
Over the next five years the trust has to cut their budget by forty six million pounds. They say they'd like to reassure the public that the level of disruption will be minimal during industrial action.
