If I had got up at that time for a wated interview I would have been upset, and I'm not a teenage boy @gingercat02 . Sainsbury's definitely employ 16 year olds - ours do anyway - as DS' friend got a job there in year 12. I hope they manage to find your son something; they can see that he is committed by interviewing at 6am!
Our local Tesco is desperate for staff but won't take until 18 years old. They are really doing themselves out of a large number of sixth formers.
DS has bounced back after a few days of arnica gel and ibuprofen, thank you for asking @steppemum. I agree, I used to take him to training and matches but I haven't for a couple of years as I just can't watch him play full contact.
DS could happily tell your daughter why extra time in bed, and being 15 minutes late would be preferable to less time in bed and arriving 4 hours early 
An aspirational timetable @anoukis is better than no timetable at all (looking sternly in DS' direction).
I'm glad your daughter has had a positive conversation with the HOD @bluefineliner, and has done well in her tests so far.
DS has said that they are going to have some baselining after half term. He knows he isn't doing the work he probably needs to do. Not getting the grades he thinks he can achieve in these tests might give him the boot he needs. Fingers crossed.
