Dang.
The system kinda reinforces no notice. P
A couple of days after he becomes fully vested he should give notice.
He should also try to document somehow that he was still employed after the vesting date in case they try to screw him over.
He should write up his resignation letter and email it to himself at work if he has email.
Then forward it to his boss and make sure to CC himself, then immediately go give a written notice to his boss.
If they really want to they could probably recall the email and he would not have the CC'd copy.
If he can access his own email on his phone he should open the email right before he goes to talk to his boss. I don't think it can be recalled once opened.
