(defendant violated MSWPA and state (OR) minimum wage law by crediting seasonal workers' on-farm housing costs toward workers' minimum wage; had housing costs not been credited toward minimum wage, wage would have been below minimum; court ruled that evidence showed that orchard could not maintain adequate workforce without offering on-farm housing and local room availability insufficient to accommodate 350 workers necessary for defendant's month-long peach and pear harvest; court also ruled that defendant violated OR law by paying workers day after harvest ended rather than on last day of work).
