Walmart

I got hired as a part time associate/cashier. I have been constantly being treated differently and reminded that I am a very slow learner. Instead of understanding my situation and trying to be compassionate while explaining to customers that this associate has disability, they stopped giving me enough hours so i can meet my basic needs. They don't allow other associate to swap or give their shifts to me, because they don't want me to work. They don't want to deal with my disability or like to put extra effort to make me successful at work. I am highly discouraged by their attitude. I am in dire need of job and trying my best to produce the best quality work, but I need support from management. unfortunately, I am not getting it. Please help. I feel very harrassed and bullied because of their attitude.
