I would not work for minimum wage as an EMT-B or Paramedic. Working minimum wage hurts our efforts to be viewed as professionals in my opinion as much or more than volly's.
I work with 3 different services, heres the starting pay for each level starting with the lowest paying and ending with the highest paying service per hour.
EMT-B $9.00 , $11.00 , $14.00
EMT-I $9.50 , $13.00 , $16.00
EMT-P $10.00 , $15.00 , $18.00
Yes I can make more money still in other careers, but this covers my expenses and supports my family. Cost of living is cheaper here than in many parts of USA as well.
