Well boys and girls I've been doing this for a touch under 10 years. I am also a college student and I hope to get out when I graduate but it is solid work and I can't complain about where I am.
My shop is not a union shop but there are meatcutters unions. I still make decent money, it isn't a ton but I can care for my family and have some money left over. If you get into management in a midsize or large company or even a meatcutter in a union you can make a decent amount of money.
Honestly the trade is dying. I can break down a whole animal because when I began work it was still commonplace to get hanging cattle or lamb, and break down the entire animal (or half carcass), I can also make sausage from scratch. I have even spent a few years breaking down deer, which is much much different nowadays as well. Most grocery stores or butcher shops do get their meat broken down into the primals and cryovaced. As a meatcutter you will portion and trim the primals, tray them, maybe help customers, display the product and change displays with seasons and sales.
It isn't hard per se, but it can be hell sometimes. 8-12 hours on your feet in 50 degree or less rooms, covered in blood, tossing around boxes that can weigh well over 100 lbs. All of your joints will feel it. I know many guys with carpal tunnel, bad knees, bad backs etc. I can already feel the carpal tunnel setting in. Then there is the equipment, you will have to know the ins and outs of cleaning, sharpening and making minor repairs on every type of knife you can imagine, wrapping machines, freezer/cooler cases, band saws, meat slicers, choppers, patty machines, sausage pumps, grinders, etc.
You will also likely have to learn all about work safety and food handling. Take it seriously if you are going to do this. I have a couple buddies who have lost fingers, had nerve damage or have had to get stitches for some pretty serious gashes.
I'll check this thread later if anyone has any questions/comments.
BTW, where I live choice skirt steak is pletiful and runs 5.99-8.99 depending on where you go. You can definitely purchase cases of it, we buy four to six 60lb cases a week at my shop. The price spike in skirt steak is due to it growing in popularity, just like the flank steak, it was dirt cheap a few years back but thanks to Food network and the like people actually know about these awesome cuts that were once the butchers secret. And, there are actually four skirts on each animal, two inner and two outer, they are located on the plate of the animal. The inner skirts are wayyy better, much larger and uniform in shape than the outer skirt.
