Big disappointment - Field Technician Spectrum Employee Review

One month of classroom training, and two weeks of highly unorganized field training with mentors who really don't want to be mentors is nowhere near enough training for people who have never done work like this (like myself) before. I told my managers from the beginning that I had no experience in this field, they invested a bunch of money in me (and other new hires), and at the end of the two week mentor training, basically said "We don't feel safe with you working out in the field by yourself, so you have until the end of the day to show improvement, or we have to find out what to do with you." Essentially, that translated to "We can fire you, or you can quit." Starting pay for this job (in Southern California) is just north of $18/hr. For how much work most jobs required, and how much danger is involved in this job, starting pay should be no lower than $25/hr.
