Workers’ compensation — Temporary disability benefits — Voluntary limitation of income — Availability of employment — Judge of compensation claims erred in rejecting employer/carrier’s affirmative defense that claimant voluntarily limited his income by refusing suitable employment after claimant was terminated by employer — The fact that suitable employment is terminated is not determinative of the defense — Because it is not clear whether JCC based her ruling on more than a lack of continuous offers of employment after the date of termination, rejection of E/C’s defense is reversed — On remand, JCC shall make findings addressing the continued availability of suitable employment, claimant’s refusal of such suitable employment, and any justification for a continued refusal
