Edward,
What sort of work do you do at the moment?.
The reason I ask this, is because nobody starts at the top, in any Trade, especially as a Liney, ask anyone who does any sort of Line-oriented job, they will tell you that it is really hard yakka, because of the fact that the equipment and wires are so large.
You also get used to working really long hours, in the worst of weather and you are normally on-call pretty much most of the time.
I do a lot of Faults work over here in NZ and when it last snowed over here, I worked for 4 days non-stop, putting poles and lines back up, as part of a Line Crew.
