Here’s my advice about getting your parents involved in your employment prospects, at any age above about 14:
Seriously. It looks really, really bad for the parent to do anything more than casually inquire “oh, are you guys hiring, because my child is looking for a job”. If they say yes, from that point onwards you’re going to need to do EVERYTHING yourself, because it looks really, REALLY bad to be reliant on your parents.
If you have dysfunctions related to autism that makes it hard to apply for a job, you’re going to need to talk to your prospective employer directly to ask for certain allowances to be made. Don’t rely on other people to make your life easy, you’re going to need to do the work yourself. Now, if one of the allowances made is that you have some kind of advocate to help you out as needed, that’s totally fine, but you’re going to need to be the one who makes the effort to tell your prospective employer or employer that.
If you have dysfunctions related to a job that make it impossible to apply for a job, you’re going to need to seriously consider if it’s appropriate for you to be working there at all. I hate to say it, I really do, but practicality must prevail and you must remember that employers care about the money, not you. To them, you are a fleeting blip.
For that same reason, try to limit the allowances you ask for to a bare minimum. Employers will not employ a person if they’re going to be more trouble and they’re really worth, and as illegal as it may or may not be it’s also totally accepted practise. Accept that there will be assholes out there who hear you’re autistic, and immediately put your application in the “reject” pile. However, mentioning it is never something that you can definitely say yes or no about, but rather it’s something that must be approached on a case by case basis. Mention it when you think it’s appropriate to what you might be employed to do. Don’t bother mentioning it if your primary problem is having too many people around, if you’re going to be a night-shift worker stacking shelves in a warehouse. Do mention it if you’re going to be working in a technology store, and you can’t be around too much noise (i.e. the music section).
On that same note, know where to draw the line between a reasonable expectation of allowances to be made, and an unreasonable expectation that the employer will create a brand new job for you. If you melt down when there are too many lights and colours around you, it’s a bad idea to apply for a job in a party shop. If you have difficulty coping with large crowds of people, don’t apply for a job as a cashier in a supermarket. Employers won’t bother to create new jobs for you, they’ll just fire you or not bother to hire you.
So, in conclusion, you’re going to have to use your best judgement about this. If you need allowances for a job that isn’t directly triggering but might have triggering elements, tell them and ask for the relevant adjustments to be made. If you need a new job created to be employed there, find someone else to employ you.
