I'm thinking of refusing to work with an autistic kid
Why would you refuse to work with an autistic kid?
I don't know what I'll do in the situation.
While it's understandable that you have concerns about working with a person with a disability like autism, it is not appropriate to refuse to work with that person outright. People with disabilities should be treated just as like everyone else or otherwise they will feel singled out and will suffer emotionally. You shouldn't refuse to work with an autistic person and instead try to be more open minded and make your best effort at working together as it will likely turn out not to be a problem.
I really do not know.
You should work with this kid, I'm sure it would really help him out and you will feel good about doing it.
