hawker750 - to base your decision on whether or not to employ CAPTAINNIC on the wording of one sentence does not show a whole lot of wisdom or common sense. However, I suspect that you are probably not in a position to employ anybody, so your dilemma will be removed from you.
I can only concur with other contributors here. It may indeed be true that $6,000 is a lot of money in Kenya. That is largely irrelevant for any ex-pat pilot employed there as almost certainly they will have mortgages to pay and family to keep somewhere else around the world. They therefore require to be properly remunerated. Nothing sinister or greedy in that - just plain common sense.
