A business coalition has launched a new ad criticizing DFL Senate candidate Al Franken for supporting legislation that would make it easier for workers to start unions.

The ad by the Coalition for a Democratic Workplace takes aim at the Employee Free Choice Act, which would certify a union as soon as a majority of workers at a plant signed cards authorizing it. Current law allows employers to demand a secret ballot election when their workers seek to organize a union.

The ad features actor Vince Curatola, who played the mob boss Johnny (Sack) Sacramoni on "The Sopranos," staying in character and praising "My pal Al." Then an announcer urges people to call Franken and tell him "he's wrong to end worker privacy."

Franken spokesman Andy Barr says that rather than take away workers' rights, the bill prevents corporations from intimidating workers.
