ORS 656.212: Temporary partial disability.

When the disability is or becomes partial only and is temporary in character:

      (1) No disability payment is recoverable for temporary disability suffered during the first three calendar days after the worker leaves work or loses wages as a result of the compensable injury. If the worker leaves work or loses wages on the day of the injury due to the injury, that day shall be considered the first day of the three-day period.

      (2) The payment of temporary total disability pursuant to ORS 656.210 shall cease and the worker shall receive that proportion of the payments provided for temporary total disability which the loss of wages bears to the wage used to calculate temporary total disability pursuant to ORS 656.210.
