I am currently a high school senior. I have volunteered in an ER for the past two years. This summer after I have been considering working as an ER tech (not neccessarily at the hospital I volunteer at). What do you think my chances of being taken seriously are, given I have no formal training past first aid and CPR, will only have recently graduated HS, and will only want to hold the job for the summer. Also what is the best way to approach finding a job? Presently, I can find no listings for a ER tech position open. Should I just call the hospital and explain what I am looking for?
