A Missouri house committee has endorsed a measure known as “right to work” that would bar labor contracts from requiring that all employees pay union fees. The house workforce development and workforce safety committee also voted yesterday to advance legislation that would change how unions can collect fees. It would require unions to get annual written authorization to collect fees that are automatically deducted from a worker’s paycheck. If they clear the legislature, both measures would go on a statewide ballot. The republican sponsors say sending bills to voters would get around a likely veto by democratic Governor Jay Nixon.
