Mary Beth Schneider, writing for the Indy Star, has an interesting article about a legislative priority of the Indiana Chamber of Commerce to prohibit allowing voluntary deductions from teacher paychecks for payment of union dues. They don’t particularly want to apply this prohibition to other public sector unions like firefighters or police.
No principled reason for this hangs together if you single out a particular kind of public sector union. But, principle doesn’t have a lot to do with this aside from the principle that “unions are political opponents and we’d like them to be weaker.”
The article suggests that, with the wide availability of automatic withdrawals or payments from bank accounts, the elimination of deductions from paychecks might not be as big a deal for the unions as it once was. Still, it’s fairly clear that this initiative is little more than union bashing.
