I actually work at a call center, and yes some days I just dread it BUT at the end of the day I just...do my job correctly. Only one person over the phone has called me out on it but they were a hostile clien we knew about to begin with...ANYWAYS my point is just go and do your job and try to do it right. And also look into a disability claim or some type of note on your file. Your job has to try to accommodate in some way/shape/form.
