I think "claim or demand" relates to money owed to the state.
I still would like to see the bill passed anyway, and the gov impounding the union dues money until such point as the thing is sorted out.
Could be. It's my understanding that public employees are required to join a union and dues are automatically deducted from their paychecks. If that's correct, wouldn't eliminating that requirement and automatic deduction of dues be releasing a claim/demand of the state on their paychecks?
