Job satisfaction was the main reason, I had actually worked as a hospital porter previously for more money......plus I'm 18 so the pay was actually quite good anyway and it must be one of the best job's someone can get at that age before going to study for a university degree or in my case an ATPL.
Reason I'm asking was that I felt the skill required was severly undervalued and wanted to know if this was the case universally and not just my own company.
