I have been working with my boss (an attorney) for over 5 years now. I have been a loyal assistant and have followed him to one other place besides where we are now. Since he opened his own practice a few years back he has 2 associates. Just recently he hired another secretary to help with the workload but it seems she has taken over my job. We are assigned to cases and not attorneys. I feel demoted, almost like I am on the way out. How do I approach my employer about this issue without sounding so petty?
