Did you ever feel that whenever you move the Reasonable Accommodation process forward, the goal line keeps getting pushed back just out of reach. The ADA requires employers to engage in a dialogue with you about your disability and the accommodation you need. This is called the interactive process and the EEOC is very clear about what it means and that an employer is required to participate in good faith.
Sometimes, all that matters is that in the end, you are accommodated. But a lot of times, your disability flares up and you are not accommodated while you navigate the RA process with a reluctant manager. If you are harmed when this happens, maybe by being forced to use your own leave or your health is hurt while your RA request is being considered very slowly, you may be entitled to an interim accommodation.
