Welcome Gus! Apprenticeship is an awesome way to learn and earn a career! Ive never been a day without a job after my first 10 years in a dirty nasty TV Shop, (it seemed like a cakewalk after 4 years of the regular army). It paid like crap, the hours sucked bad, I got called things by my bosses my Drill Sgt wouldnt have (My nickname from Grumpy Old George was "You Clutzy Phuck") and there were no benefits to be garnered except the biggest one; my brain was a little fuller at the end of a hard day than when I started it! My starting wage in 1984 was $1.50 an hour and all the soda we could drink (Fridge was always full), 26 years later and I make more in one hour than I made in 20 in the TV SHop.
That said, apprenticeships are getting tougher and tougher to find, most professional jobs require a college degree as a prerequisite. Most younger folk expect way to much out of the blocks; they want great pay, good bennies and an education even if they dont have the trade under their belts the day they start working. Most small to mid sized businesses cant and wont provide all three and those, they wont take the risk and the time to apprentice you but if they do, they probably cant pay you much and teach you at the same time.
I averaged 60 hours a week and probably got paid for about 40 with lots of nights and weekends, it was worth every minute of it cause I left that shop with something worth more than a paycheck, a skill that has kept me employed well and compensated reasonably ever since.
There are other ways of getting that education, The US Military has Armor Specialists in every category you can think of. When you get out, others will be much more likely to give you a try. Good luck and glad to have you here, enjoy!
