Nine months into the coronavirus pandemic and some Wisconsin businesses are barely hanging on.  The October coronavirus business and economic impact survey by researchers at the University of Wisconsin-Oshkosh illustrates how critical the situation is.  Nine percent of Wisconsin businesses say they have no more than three months before they will have to close for good.  The poll-takers are finding a sharp decrease in business confidence in the state.  They say they don’t expect any more federal help and figure the pandemic will continue to impact day-to-day operations for anywhere from nine months to a full year.
