Bales, I don't get sick pay. If I don't work or work less, I can't pay my bills. If I can't pay them, we lose the house both boys have lived on for most/ all of their lives. I don't feel that would be in anyone's interest.
If my DSs were out of control (oh, I know I'll probably be told they are, and I'm too stupid to see it...), drinking, smoking, fighting, being brought home by the police, staying out late, being violent, I would probably try anything, including giving up my job (and taking the awful and pretty immediate financial consequences).
But they're not. Yes, they are a long way from being perfect. I do my best to impose rules and discipline. Which is not easy when I'm doing it completely on my own. Not to harp on about it, but I have no family, no help from my Ex (who isn't DS1s dad anyway), and until fairly recently I'd been single for a very long time. I don't have male friends, my DC don't have any positive role models other than me. I've done my best. Not as good as some, better than others.
As it stands, the worst that will happen if he doesn't improve is he might not get to uni. Or go but flunk out. It would be nice if he went, I hope he does, but there are lots of alternatives if he doesn't make it. I certainly won't view him as a failure if he doesn't go - some of the most successful people I know left school at 16/18. As a previous poster said, a spell of menial work might help him (this is why I'm encouraging him to get a pt job...)
I don't dispute I should be told if he's not at school.
When he was younger I never objected to being asked to pick him up if he was ill.
My issue now is being made to feel that it's all down to me, and on no way to DS. As said, I feel in the school's eyes it should be his responsibility to get himself to school. I should (and do) support that, sanction him for lateness pr missed lessons.
In the past, my issue was that his (previous) school insisted not just on him being collected if ill, but within a very short timescale I couldn't meet, working over an hour away. And that they insisted they had to be able to reach me at all times. Even though they wouldn't always be able to reach non working parents immediately. It was that unfairness that annoyed me. But it's long ago,a different school and I should probably let it go.
