Gov. Mark Dayton on Friday vetoed the one bill to emerge from this session's debate over unionizing child-care workers.

The Republican-backed bill would have prohibited union dues and fees from being deducted from state child-care subsidy payments. The DFL governor said in his veto message that the bill is "unnecessary because no union representation of child care providers exists in the state of Minnesota."

"I will not support such a misguided and unnecessary effort," he said.

The bill was a response to a union drive among in-home child-care providers, which has stalled. Dayton's order calling for a union election among providers caring for children receiving subsidies was thrown out by a Ramsey County judge.
