Attack on Flint history yet again.

Flint -

(12/13/2012) Vandals have painted a historic site marker in Flint that pays tribute to the city's deep roots in the union movement.

Green paint now covers the gold lettering on both sides of the sign.

The sign stands proud along Chevrolet Avenue on the campus of Kettering University.

It's across from the old Chevy in the Hole site.

The words on the plaque tell the story of the Sit-Down Strikers back in the 1930's.

It was the union movement's most famous victory in the fight for labor rights.

The strike led to the recognition of the U-A-W by General Motors.
