First, in your opinion, what would be a reasonable amount to give his girlfriend? Second, assuming you were the apprentice in the story, would you abandon your training or would you have given in to the pressure to split the money with your boss?
Difficult questions to be answered, because even for law lawyers this is an answer that varies a lot from the personal interpretation of the case and the details of the circumstances.
In the first case, the right thing would be to give all the money to his girlfriend, after all, the man used money that was not his, did not warn (stole) and acted with extreme coldness when trying to return only the 10 thousand trying not to be noticed.
Obviously, the yield of this amount was the result of luck or the man's effort, so maybe he deserves some part, but in my opinion it would be less than 50%.
I agree with you on this, since the money is from his GF's purse the winning proceeds should be 100% given to his gf, the girl is a little generous because she only asked for 50%.
In the second question, obviously the apprentice should keep 100% of the profits, because he used knowledge he acquired, with his money and effort or luck. The boss doesn't deserve a penny.
There is an agreement between the apprentice and the boss where the boss will take care of the apprentice's needs while the boss has the authority over all the assets acquired by the apprentice during the apprenticeship. That agreement made the boss have the right to the lottery wins, this time the boss is actually being generous.
if the money belong to my employee - I would not claim it.
