It's not often that you get unsolicited feedback from people you manage. For the past 2 years I've been on a project in which I managed supplier teams through a major transformation. At times my personality came through and I served as their ally, but my job was to make a lot of demands on them and make sure they met commitments. In fact, my client feedback after 3 weeks on the project was that I need to be a more of a bitch.
Despite that, the person at the supplier who was my primary contact just sent me a touching thank you email. My favorite favorite part, that I think tells so much about me:
"[You were] always asking for more, sometimes difficult but never impossible."
This just makes me smile. I'm so thankful for this.
