When Henry Godman’s workers were turning out thousands of pairs of shoes in a downtown factory, the Columbus businessman did not have to worry about calculating health insurance benefits because there weren’t any. That business from the late 1800s is long gone, but the Godman Guild, a social services agency, has about 2 dozen workers who do receive health care as part of their benefits package. The Guild was recently hit with a steep and unexpected 23 percent health insurance increase.
