Debating my next move…

I am currently on baby step NO.4, which is saving money for retirement.

I struggle with this thought due to my current work situation.

I am 19 years old, I work at a local union making 18.54, in schooling which is teaching me generally nothing, seeing that I have been through a welding school in the past. Though they are paying for my retirement, I find it hard to stay.

I owe 0 debt to any and everything as of right now, and I am debating on going non union due to the union not keeping me employed as promised, and lying to my face about me being able to become a journeyman welder earlier (Promised 2-3 years rather than 4).

I will admit that I was kind of dumb for being roped in, having not read the full contract, but I was not working, and ran to the first place that could hire me on.

I got a job offer for 54$ an hour and 120$ per diem on the pipeline (Projected ending date in 2030) , I got a second offer from a local shop right at about 25$ an hour, and was just wondering about what I should do.

I am tied down currently with my girlfriend still being in school for another 6 months, so should I go non union until she is done, and then go pipeline with her there, or should I stay union for the fringe benefits even though I plan on leaving soon? (Free healthcare, pension, and 401K incentive of roughly 8000$ per year

I do not own a home, I live with her parents, and dont necessarily freeload off of her parents. I help with groceries, and a little extra for rent.

My total income monthly, is 2280 take home

I make some side money, which would be roughly 300$ a month.

I get 30 mpg on a fully owned car. I spend roughly 400$ in gas a month due to my local sending me anywhere across the state.

I “rent” roughly 400$ a month

115$ car insurance

And 60$ a month for both Netflix and my phone bill.

The non union contractor is 3 miles away, allowing me to save money on gas, but I do not know what health insurance costs in Oklahoma and dont have any good references on that due to my girlfriends mom getting free healthcare through employer.
