Hundreds of personal care assistants are stuck in limbo due to a backlog of background checks in Minnesota.  WCCO reports around 950 people are waiting for their background checks to clear before they can start getting paid.  Tammy Heuer told the news outlet she submitted her background check to the Minnesota Department of Human Services nearly three months ago, but it’s still processing.  She also said Cambridge home care agency that hired her is otherwise ready to get her working.  In a statement, a DHS spokesperson said they’re working to resolve the high volume of applications, but most are typically cleared within a couple of days.
