A divisive proposal in the Oregon Legislature that would require employers to pay farmworkers overtime was shuttled on Tuesday to a joint bipartisan committee to work out a solution. House Bill 4002 would require that an estimated 86,000 farmworkers in Oregon are paid time and a half after a 40-hour workweek. That requirement would be phased in over five years, with employers provided tax credits over six years to cushion the extra business cost.
