Congrats on the new job! Rabbits are super scent-orientated and can be very particular about getting the right scent on their property. Yes, you are blessed to be property
You can try the yelping method if he’s damaging your clothing or hurting you, but it often doesn’t work on bunnies who are showing territorial behaviours. Since he’s so young I assume that he’s only been neutered recently. Rabbits sometimes get a hormone surge after the procedure, so it may be a temporary thing. You may also have a stubborn scent-orientated bunny on your hands.
I hope that the yelp-method works for you, it works best when rabbits are nipping because of grooming behaviour. If it is because they have spotted an interesting scent there may be no other solution than to change your clothes after you come home.
We taught Breintje not to nip at hands with the yelp-method, but it didn’t work in another case. 2 years ago I fed the neighbour’s bunny while she was away, and my slippers became the object of a full-blown territory war. Breintje kept chinning them over and over again. I already had back issues at the time and it hurt badly when Breintje bumped my right foot. So those yelps came pretty naturally, but he kept going. I left him alone with the slippers for half an hour, but he still wasn’t done scent-marking them. In the end I had to go to the neighbour’s house barefoot with my trousers rolled up, washing my hands and feet after each visit
