Here's the link to the OE's for Dayton
http://www.iuoelocal18.org/DistrictOffices.htmLooks like Dayton is in district 4.
With the OE's, you are called for a job according to where your number is in the deck of unemployed workers and according to what machines you can operate and what counties in your district you are willing to travel to. Many of the guys, once they complete the apprenticeship, can be called directly by working with certain companies who wish to call them back for various jobs. In other words, make good friends with those who you are working for. After finishing the apprentice program, you can still go learn new machines and become certified for them at no cost at the training centers. The more machines you are certified on, the more chances you have of being called for various jobs.
My son's not working right now, hasn't had much work all year but our area is very slow with projects right now and he doesn't like to travel since he's newly married. He does make really good money when he works, but it's usually very long hours and a lot of overtime. His last job was 7 days a week, 13 or 14 hour days until the job is done. He usually works the refinery shutdowns in our area and from what I've heard, some of the work was postponed this year. He recently spoke to a friend who was going out of state to see if there was work there. His friend told him he couldn't find work in a 500 mile radius from our area right now. Winter can be a rough time to get jobs around here. As my son says, it's a matter of budgeting well and saving what you make when you work to get you through the slow times.
