4654. If the injury causes temporary partial disability, the
disability payment is two-thirds of the weekly loss in wages during
the period of such disability. However, such disability payment
shall be reduced by the sum of unemployment compensation benefits and
extended duration benefits received by the employee during the
period of temporary partial disability.
4657. In case of temporary partial disability the weekly loss in
wages shall consist of the difference between the average weekly
earnings of the injured employee and the weekly amount which the
injured employee will probably be able to earn during the disability,
to be determined in view of the nature and extent of the injury. In
computing such probable earnings, due regard shall be given to the
ability of the injured employee to compete in an open labor market.
If evidence of exact loss of earnings is lacking, such weekly loss in
wages may be computed from the proportionate loss of physical
ability or earning power caused by the injury.
