Heather:
As a special ed teacher, I am saddened to hear about your experience. I can only imagine one of my students being treated in the same manner as you have! However, it also sounds like you're better off without your old boss!!! The workplace that you described certainly wasn't healthy, especially for you. As for workplace rights, the first thing that a person needs to consider is whether to disclose his/her disability or not. Based on your post, I am guessing that you've already chosen to do so(?). Second, once an employer is informed of a disability, it's my understanding that you should take a proactive approach. Emphasize to your boss that you don't want to get out of doing any work, but, that to do your work more effectively, you have some suggestions to make. (What is it that you think would help you do your job more effectively?) I'm not sure what your boss legally is obligated to do. My guess is that they should make resonable accommodations for employees (i.e. a ramp for an employee in a wheelchair, an extra day for the report, etc.). What do you think?
Wish I could be of more help here. I DO know that this info is on the web somewhere, I just can't recall where!!! Oh well, "old age" I guess...... If I do think of the site, I'll let you know.
