[61] From the perspective of the plaintiff's superior officers and his work colleagues his performance still remains of a high standard. Three of his work colleagues gave evidence. The first of these, Mrs Normington, the Human Resource manager, was able to compare the financial impact of the plaintiff's transfer to the Network Unit. I accept her evidence that the transfer was a promotion for the plaintiff and resulted in his obtaining a higher salary.[57] Indeed, the summary of the salary paid to the plaintiff (ex 41) shows steady, progressive increases in his remuneration after the accident. His promotion as generation manager in the Network section was significant in this regard. There was no detail as to what would have been the plaintiff's earnings had he stayed in the Business Development Unit. Had he remained in that unit it seems likely that when Mr Behrendorff left on 30 June 2002 the plaintiff would most likely have succeeded him as he had previously acted in the position. As at that date the salary differential between the two positions was $9,000 gross ($104,000 - $95,000)[58]. That potential to earn a higher income by replacing Mr Behrendorff would only have been realised if the plaintiff had stayed in the Business Development Unit on a lesser salary than he received as generation manager following his promotion. There is no precise detail of that differential and in the absence of the detail I am not able to quantify any possible loss of past earnings on this account. I propose, rather, to include the likely shortfall for this loss of opportunity in the global assessment of the plaintiff's lost earning capacity stemming from his injuries.
