I recently left a support contracting position after several years of working very closely on site with my government clients and other support contractors for a new position with a new company in a completely different location. I have no intention of returning to this company or location (Relocated from Florida to New York).
After leaving, I am now receiving multiple phone calls and text messages a week to my personal cell phone number during work hours at my new position. The questions are for generally minor requests related to my previous responsibilities for which I was a lead for several years and are from both the clients which my company used to support onsite and my previous coworkers with my previous company.
I gave a full two weeks notice and attempted to document as much "tribal knowledge" as possible before leaving while making myself available to those below me in my role for technical questions/training. Some questions/messages mostly from my previous clients who did not want me to leave, have been more personal such as mentioning how my previous counterparts are overwhelmed and I am greatly missed.
I generally hesitate to respond and when I do so it is a brief objective message, where I may give a small amount of knowledge but encourage them to reach out to a specific individual who may know the answer still working for the project.
I find this behavior slightly unprofessional and disruptive when coming up to speed on a new position. what is the appropriate professional way to handle these requests?
