Lil Juiced Coupe, before listening to these guys make sure you can spell better than they can. HA ha ha. Just kidding.
You grab which ever apprenticeship you can. That ticket is the difference between going for a walk and a coffee and donut and going for a walk and looking into Tim Horton's on the way by, wishing you could afford a coffee and donut. Depending on where you work, millwrights make $30 -$40 per hour. Same goes for most trades people. If you can pick which one you want, the machinist trade will suit your desires better than the millwrights trade.
Millwright means factory mechanic, it is composed of 25 different venues of trade. Millwrights are basically "Jacks of all Trades" and masters of none. They like everyone else, all have strong and weak points. Usually dictated by their places of work. Some Millwrights, because of work conditions, are nothing more than high priced laborers. Some are incredibly gifted at almost everything they do. Again, it usually depends on the job required and the willingness of your employer to broaden your skill levels.
Getting the ticket is just the basis of a huge learning curve to skill and the mental parameters to deal with many diverse situations from every day hum drum to extreme hazard or stressful conditions and take it on with confidence, while exercising proper safety and acceptable methodology to each situation. It isn't rocket science by any means, none of the trades are. If you're a lazy individual, don't become a tradesman, there is nothing worse than a mickey mouse tradesman.
Millwrighting can be interesting, boring, dirty, clean, hard work and smart work. It can also be monkey work but they don't pay for what you do, they pay for what you're supposed to know. Much of any trade, can be easily done by any non skilled or handy individuals. If you do your job well, even the really difficult procedures look simple.
Take the plunge and do it, it will make you a lot more salable to an employer, and when it comes to lay off time at christmas, you will be working but at 2 -3 times regular rates. It isn't uncommon for tradesmen to make $5000 over a week long Christmas shut down. Apprenticeship wages can be extremely difficult to get by on in the first year as well. The good news is, you're guaranteed a raise every year, as long as you pass the exams.
