Your employer is bound by law to make reasonable accomodations for you. If your emoyer feels the accomodations you need are beyond what is reasonable, then they will fight you on that. Do you think there is any merit to the position that the concessions you need them to make are too burdensome for them to allow. You do have to try to look at things from their perspective to come up with an understanding of what is fair to expect. No employer wants to take on an employee, when it looks like it is only a matter of time before that employee will throw in the towel and stop working with the expectation of collecting disability insurance that the employer had to pay for. That's not fair.

Actually, I'm not clear on how this disability insurance that your employer pays for works.
