I am now training a client’s employee because of something

I am a consultant that has a client for about 4 years. Last hurricane season he had a network crash and had to pay about 8k to get it all fixed. Now he said he is going to use one of his office people to do the day to day work, and I will do the once a month system updates for about 3 hours as he puts it. He also wants the office person to watch me as I do the updates so he can learn them. Any experience from anyone out there with this type of situation.

Am I about to lose a client to an office assistant, or not?
