Happy Hooker, Did you miss my post or something? I turned 18, virtually the exact same situation, and the sixth form KICKED ME OUT. They can absolutely legally do this under the fact that they are responsible for children. There is no benefit to telling. Different story for uni though provided you're not on an NHS funded course.

At uni, telling people I'm a sex worker has given me the benefit of some of the best friends and acceptance and total lack of isolation (as opposed to some workers on this forum) and I would absolutely recommend it to those comfortable, though of course only to those who don't mind if their parents find out or something (mine knows) so still a minority. This year I will be announcing in front of uni officials that I am a prostitute in order to attempt to pass a motion that will stop the uni from being able to reprimand us for doing out jobs. If it passes, next year I intend to take it to a national level. I've whole heartedly decided I don't give a shit, but then in my job it is not going to matter as much because I'll be a sex researcher. So.. case by case basis, but never ever at an establishment which predominantly children attend. And re: uni - NOT if you are on an NHS funded course because their rules about sex work and disrepute are much clearer and harder to argue against.

College and university is a different thing...you're a bit older for a start with no parental involvement.  I still wouldn't do it but each to their own.

But OP is just 18 and it's her sixth form college.

DON'T DO IT-for sooo many reasons but one is that you get some really nosy teachers and if you have younger siblings they might call social services thinking something went wrong at home for you to be doing this and so your siblings might be at risk of harm too.It could even affect what grades you get even though it is completely wrong I know a boy whose grades from a certain teacher (in secondary school) got worse after said teacher found out he had a criminal record so just be super careful.
