Inver Grove Heights, MN (Learfield/MNN)  --  Supporters of a sociology instructor at Inver Hills Community College think his teachers union activities are why he has been suspended and banned from campus.  

Fifty-two-year-old Dave Berger has taught at the school for almost 25 years.  The union approved a no-confidence vote against the school's president last month.

A spokesperson for President Tim Wynes denied Berger's suspension is a case of retaliation.  The faculty union website alleges past intimidation and threats of reprisal when members have criticized the school's administration.
