If you dont mind me asking, What kind of learning disability do you have?
I also have a learning disorder too, mainly dyslexia, a bit of dysgraphia and some language disorder. But still I have managed to get a job without any problems. Although some tasks can be difficault, but not impossible and does take me longer to practice then others. But I manange.
I work in this cafe at a hospital, it gets very hectic and some ask for really confusing stuff, I often just forget what they have said and it's really hard to follow certain instructions, (you get people asking for, 4 teas and 2 cuppicinos and then they say, can I have 3 less milky, two very strong and 2 with extra sugar and the others less hot). I just get so confused. It takes me longer to count the money too, and well pronouncing some words and sentences is hard too. I often say, would you like eeffoc milky or eat less strong, it's annoying and the Doctors there always asking me if I have dyslexia, it's very embarrassing sometimes.
But if you don't want anything bad to happen, you really have to tell someone, they will find ways of making your job easier and cant force you to do something that's impossible. You have rights.
