| 1. Benefit and duration. While the incapacity for work is |
| partial, the employer shall pay the injured employee a weekly |
| compensation equal to 80% of the difference between the |
| injured employee's after-tax average weekly wage before the |
| personal injury and the after-tax average weekly wage that the |
| injured employee is able to earn after the injury, but not |
| more than the maximum benefit under section 211. Compensation |
| must be paid for the duration of the disability if the |
| employee's permanent impairment, determined according to |
| subsection 1-A and the impairment guidelines adopted by the |
| board pursuant to section 153, subsection 8 resulting from the |
| personal injury is in excess of 15% to the body. In all other |
| cases an employee is not eligible to receive compensation |
| under this section after the employee has received 260 weeks |
| of compensation under section 212, subsection 1, this section |
| or both. The board may in the exercise of its discretion |
| extend the duration of benefit entitlement beyond 260 weeks in |
| cases involving extreme financial hardship due to inability to |
return to gainful employment. This authority may not be |
| delegated to a hearing officer or a tribunal of hearing |
| officers as approved by the board, and such decisions must be |
| made expeditiously. |
