Employers are turning to the Rock County Job Center for help in finding qualified workers.  Southwest Wisconsin Workforce Development Board CEO Rhonda Suda says more than 40 area companies have signed-up for an upcoming virtual job fair.  Suda says many employees are finding the current job market very favorable and are exploring their career options.  She says employers are finding it difficult to fill positions, and that is causing delays for planned business growth.  The virtual job fair is planned for next week Friday.  Participants can learn more at Wisconsinjobcenter.org.
