The Labor Relations Commission may, if there is either of the following causes or events, impose the charge for compelling performance, ex officio or at the employer's request, after the cause or event terminates:
1. The employer has objectively made efforts to perform the order for remedy, but it is evidently difficult for the employer to perform the order for remedy because of the employee's unknown whereabout, etc.;
2. If it is difficult to perform the order for remedy owing to a natural disaster or any other unavoidable cause or event.
