The Senate on Tuesday sent Gov. Mary Fallin a bill that would strip collective bargaining rights from city employees in Oklahoma's largest cities.

House Bill 1593 passed Tuesday on a 29-19 vote supported entirely by Senate Republicans.

The bill would repeal a state law granting collective bargaining rights to nonuniformed city employees in cities with populations of more than 35,000.

Labor unions and Democrats criticized it as an unfair union-busting tactic, while Republicans argued that it simply lets local officials decide whether to bargain with unions.
