A lot of good information. Thanks a lot for this.
My current job is just a vendor for Budweiser and we don't get paid shit for the amount of work we do, but the main issue is there's no room for advancement. I've been offered a "promotion" from a delivery driver to salesman, but the drivers make more than the salesmen and given how little they already pay us, I can't make ends meet if I move to a sales position. Past the sales position, there's nothing else other than management and with the amount they get paid, they will never leave willingly and I can't wait around as a salesman for years and years hoping someone will get bored and quit or screw up and get fired.
The union job being offered to me is another delivery job and I would be just another delivery driver, but the pay is much higher and the benefits are much better as well. It would basically be a straight upgrade from where I am currently, but I'd be working extra hours. I'm currently salary (less than 40k), but this union job is hourly with guaranteed 40 - which at base-pay and 40 hours a week for the entire year still comes out to over 50k gross (not net) annually. I don't mind doing what I'm doing now but for more money, but I absolutely hate when my job stagnates. I prefer to keep learning and keep moving up, but with this union job, I would be just a driver with annual raises.
On the note of stagnation, the other job I'm being offered would bring me back to the oil field. I was laid off from my previous job back in 2015 when the oil field crashed, but I was employed there for 12 years and moved up to supervisor extremely fast. Not to mention how much there was to learn at the company, there was always something new to do and new to learn - I loved it. The pay was outstanding, the hours were horrible (26 hour rotational shifts), but I got paid for every hour I worked (being on overtime after two days was pretty nice too). This other offer I received would take me back to the same field of work, but with a rival company (the company I worked for closed the yard and moved out of town), but I would have the same opportunities as I had previously. New equipment to learn, new policies to learn, new ways to advance, and all the money/hours are still there.
So, it's a toss up between doing more of the same but for more money while working for a union (which don't seem so bad based on the comments), or doing what I loved doing in the past for way more money, but I'd have a lot less time to spend with my family again. I have to make my decision by next Tuesday so I'd love to hear more opinions on unions.
