I am on my way to bed, but couldn't leave this unanswered.
Is the apprenticeship more important to you or to him?
How does his employer/trainer feel about his attitude?
Is there any other transport available?
At what age do you feel he should be taking responsibility for organising himself?
In another 2 years he will be old enough to vote, to get married....somewhere between now and then he needs to grow up.
Are you supporting him financially?
Sorry about the list of questions, but these are all things that you will have to discuss with him at some point, so it is worth giving some serious thought to how you feel about them.
I have a sixteen year old son and an 18 year old son. Both have a small allowance to cover travel and lunches and some very basic expenses. Everything else has to be earned, sither by jobs in the home or a part time job. One is still at school, one is at college. both are responsible for own laundry etc, and for getting themselves up and out in the mornings. BUT - it has taken regular discussion and negotiating to get to this point, and it has not been easy. Indeed I have had a very rocky time with ds1.
My (very longwinded) point is that you are clearly very stressed by the current situation, but if you have not set out clearly what you want and expect, you can't expect him to change overnight. You need to have the conversation and set some ground rules.
If you have promised you will wake him, and drive him to work, then you will have to do it this time, but, if it is feasable, tell him he has to get himself organised in future - provided there is an alternative way for him to get there.
Try to have a calm discussion at a convenient time, rather than a big row.
I have been where you are, and it is possible to turn things around. And yes - they are just like large toddlers. And they do get better, but they need as much parental input at this stage as they did when they WERE toddlers!
