I am thinking about asking for a change in staffing in my program. My co-workers (teaching assistants) keep harassing me, because I am spending "too much time on the computer". They have threatened me, saying they are going to start documenting the time I am spending on the computer and report me to the supervisor. My place of work requires I use the computer to check emails, and do paperwork. My co workers do not know I have a disability. I have mentioned verbally that, "I have difficulty reading materials on the computer and could use a little help with paperwork", to my employer, but no action was taken. I am thinking of putting my request in writing. What is your advice?
