I have to agree with most the guys on the board. My old man was glue collar guy GM. He also built every home he lived in himself, well and his child labor force. My mothers side have a contracting business electrical. I myself am the only Grandson/Son in any trade out of 5 boys counting my consents.
I have worked, mason,ash-fault, concrete form, carpenter,millwright. I Finally decided electrical was the way for me to go. Make no mistake, The trade is not really hard, what happens if you have a switch up side down, it says NO !!! on it. LOL
My day today was like this. Sunday morning have to get a JOB finished and its out side underground work second day of rain. Pipe and trench went in yesterday 360' trench 2 hours nothing but a down pour. Today 1200' #10 wire back fill Mud every step of the way, sticking to the boots, shorts, Just Lots of Mud.
Can your boy hack this, does he have drive. Blue Collar work you say. Labor jobs are time consuming. You need to have an education. Drive to complete a task, because the right time to do most jobs is never when you are doing them. 1200 volts Humm, that will just kill you, and all you have to do is get close.
I have seen guys fall from a shy lift, become berried in a trench, hit buy a boom from a back hoe. These things happen every day. Not because the person is not smart, or care full enough. Because the other guy was not.
Make no mistake, My parents told me it Military or collage or there is the DOOR. I took option 3. It took till I was 27, but things are good today.
Good Luck.
