For weeks, the nation's attention has been drawn to the storm in Madison over Wisconsin Gov. Scott Walker's proposal to limit the power of government unions. Yet 500 miles to the southeast, in Columbus, Ohio, Gov. John Kasich is on the verge of passing a more extensive reform.

Under the Ohio bill, government workers can only bargain for pay increases based on merit and performance, not years of service. Wisconsin's law allows workers to negotiate wage increases on seniority, but it limits increases to inflation. Anything more would require voter approval.

Ohio would limit bargaining on health insurance and reduce sick leave and holidays to what's allowed for nonunion government employees. Wisconsin has no similar provision.
