It’s not that local workers lack the skills for these positions, many of which do not even require a high school diploma but pay $15 to $25 an hour and offer full benefits. Rather, the problem is that too many applicants — nearly half, in some cases — fail a drug test.

The fallout is not limited to the workers or their immediate families. Each quarter, Columbiana Boiler, a local company, forgoes roughly $200,000 worth of orders for its galvanized containers and kettles because of the manpower shortage, it says, with foreign rivals picking up the slack.
