qcc2,
You should then consider doing a 4 year plumbers apprenticeship at SLAVE wages to then earn a qualification and a right to earn a lot if you work hard!
My brother in law has done this and earns damn good money for working (self employed ) 6 days a week , often in filthy, dirty and muddy conditions and turning a blind eye to occupational health and safety in order to get the job done at the quoted price. Not to mention the hours at night doing the paper work, chasing people for money , BAS statements etc, etc. When you work like this guy does you have a right to laugh at F/A wages...and that my friend is the reality.
