i'm just now finishing my apprentiship and its been a long process..and the pay isn't all that good at the start although if you prove you are willing to work and learn that should take care of itself.
in answer to your question if i waited for the IBEW to get into this trade i would in all liklyhood still be waiting.
i found a non-union electrician and started with him..you can always join the ibew later if you so wish.be prepared for long hours and lots of school.kiss you wife now...you aren't going to be seeing a whole lot of her for a bit.....but it was worth it good luck
