Columbus, Ohio ? A panel of Ohio lawmakers made a bill to limit collective bargaining rights for 350,000 public workers even tougher for unions on Tuesday, as the state moved closer to Wisconsin-style restrictions.

A Republican-controlled House labor committee voted 9-6 along party lines to send the bill to the full House. Its approval of the legislation was met with chants of “Shame on you!” from the several hundred demonstrators gathered outside the hearing room.

“I don’t hear your supporters out there!” one man inside the room shouted to lawmakers.

A vote on the bill in the GOP-controlled House could come today. The Senate, also led by Republicans, passed the bill earlier this month on a 17-16 vote and would have to agree to the changes before Gov. John Kasich could sign it into law. The new Republican governor also supports the bill.

Similar limits to collective bargaining have cropped up in statehouses across the country, most notably in Wisconsin, where the governor earlier this month signed into law a measure eliminating most of state workers’ collective bargaining rights. That state’s measure exempts police officers and firefighters; Ohio’s does not.

The Ohio bill would apply to public workers across the state, such as police officers, firefighters, teachers and state employees. They could negotiate wages and certain work conditions but not health care, sick time or pension benefits. The bill would do away with automatic pay raises and would base future wage increases on merit. Workers would be banned from striking.

The committee made more than a dozen substantive changes to the legislation, though it kept much of the bill intact.

Kasich’s $55.5 billion, two-year spending plan for the state counts on savings from relaxed union rights at the state and local levels. Local governments and school districts face deep cuts in the wake of the state’s $8 billion budget gap.

Those decreases in funding aren’t lost on lawmakers, said state Rep. Joseph Uecker, chairman of the House Commerce and Labor Committee.

“We have to give them something in order to help control their costs,” said Uecker, R-Loveland.

The revisions make it more difficult for unions to collect certain fees. But the committee also removed jail time as a possible penalty for workers who participate in walkouts and made clear that public workers could negotiate over safety equipment.

Democrats contend illegal strikers could still face imprisonment under laws already on the books, despite changes to the bill.

Despite the adjustments, Ohio Fraternal Order of Police President Jay McDonald said the bill was still “fundamentally flawed.”
