I've been on LTD for 4+ years. I've complied with all requirements including sending my employer Dr.'s notes at regular intervals. When I sent in my most recent Dr.s note indicating I would be reviewed by a specific date, they sent a functional assessment form to be filled by my treating physician. They said it was to determine if employment was still viable for my return to work. However, my physician hasn't indicated a return to work date. Do I have to fill out the form? Are they trying to let me go through frustration of contract? And, would I be entitled to severance? I worked for them for 20 years prior to the LTD claim.
