Legislation, HB34, changing the way the mandatory minimum wage is calculated for public construction projects in rural Missouri counties has gone Gov. Jay Nixon.

The so-called prevailing wage for a given trade in a county is currently calculated based on voluntary surveys collected and submitted by contractors on a public works project.

The bill would now require those wage surveys to be split between union and non-union wages. Then the wage would be set by whichever group, union or non-union, reported more hours of work. If there are no reports for a current year the wage, would then be set by an average of reports from the six previous years.

The House voted 93-64 to pass the measure Monday. The Senate passed the same bill last week.
