CSX lays off youngest employees most every year, sometime for months, sometimes longer. Demand rises and falls, so they hire a lot of people, then lay them off during low manpower needs and call them back up when it picks up. It takes time to train new employees and it's easier to call guys back up, rather than hire just what they need. It wreaks havoc on the young guys, but from the corporate end, it's efficient. Sometimes it backfires and they spend money to train a bunch of guys, they lay them off for an extended time, and they don't come back. Working the road (where the majority of new transportation employees end up) is a lifestyle change, and if you get a taste of being away from your family, and get laid off before seeing the income and benefits, it's easy to see why a young man or woman with nothing invested would simply walk.
As for the rest of the industries, the economy is improving overall, booming in some places, but not in our back yard. Defense spending is down after a decade of war winds down and demand is less, and coal was up for a time, and as said, the China demand has dropped off for now.
One's observation of the economy is usually only noticed from their front porch. Allegany county is not a barometer for the nation as a whole, so good news on tv doesn't always reflect us.
