COLUMBUS — State lawmakers in Ohio are making changes to a collective bargaining bill that would deal a blow to unions.

The bill now would prevent nonunion employees affected by contracts from paying fees to union organizations and would ban automatic deductions from employee paychecks that would go the unions’ political arm.

Those were among more than a dozen changes to the bill that a House committee adopted Tuesday before they briefly recessed. The panel planned to return later for a likely vote on the measure.

Other changes include removing jail time as a possible penalty for public workers who unlawfully participate in strikes and making clear that public safety workers could negotiate over equipment.

A full House vote could come Wednesday. The Senate would have to consider any changes.
