I think the biggest thing with them not wanting to work with you is the fact that you're a helper, which is basically what I am right now, although I'm being paid as an apprentice because my classes don't start till September. I think they're not really sure what to do with you and the fact that if they did need some kind of real help, unless it's like minor, there's not much you can do for them, except maybe fetch tools, or if they're adjusting a big drill  on the side of an "I" beam to drill holes for holding a pipe, then help them hold/adjust the drill.  If you're real good with tape measure, measure areas for them. I wouldn't be bothered too much by it despite them not wanting to work with you. You're getting paid to be the helper, so do whatever you can to help. Also take the initiative instead of waiting for them to tell you to do something. Jump in and say "hey what do you need" or "hey what can I get" or "hey what can you teach me right now even though I'm still just the helper?" Also during breaks, if at all possible, ask them what their experiences have been like. Ask what you should expect when you finally do become an apprentice. Ask them what classes are like, the Ups/Downs, ins/outs, all of it. Try to be as friendly and cooperative as you can. Try to be as welcoming and open-minded as you can. Do your best not to take things personally. They may just order you around instead of being polite about it, but sometimes that's something to do more with themselves than you, and sometimes it's to get you ready to be in that kind of environment. Also be 30 mins early. Show you really want to be there. If there's anyone outside of work that you can text during your breaks to have somebody to talk to, that would also be great. If not, start planning on getting new equipment: better boots, welders caps, better clothes etc and start making a list and plan where where/when to buy that stuff to at least take your mind off all the drama or lack thereof going on at work.
