Union president Robert Kelly said Claypool has engaged in a public misrepresentation of work rule issues at play in upcoming labor contract talks.
Kelly said Claypool has not spoken to the union about any of the issues that he has publicly criticized.
"I think this is a ploy to get the public angry at us because I'm assuming now that they're probably leaning toward raising fares in 2012 and they need a reason for it," Kelly said. "The Unions have become the scapegoat and we're not going to let that happen."
Claypool has singled out paid breaks and overtime rules as places where he'd like to make changes to close a $277 million budget gap.
