This is a real interpersonal conflict that happened to me.
I had just become the Publicity Head of Chemical and Environmental Engineering Students' Society (ChESS) and I had to design a poster for the first event, the distribution of examination welfare packs to the students. After receiving instructions from the Welfare Head on what to include in the poster, I happily designed it and sent it to her.
The poster was to be mass-emailed the next day as the event was just a few days away. During that week I had 3 upcoming tests and I was very busy, tired, stressed out and only too glad to be done with the poster.
To my chagrin, upon receiving my poster, the Welfare Head smsed me to tell me that I had forgotten to include the detail, "For Chemical and Environmental Engineering Students Only" and asked me to redo the poster. I was shocked! I did not recall that she had asked me to write that in. I had perused her instructions very carefully and I did not remember this line.
Irritably I replied her and told her that she could not expect me to re-edit the poster if it was her negligence. In fact, it was written in the rules for poster request to publicity: if the details were not properly given beforehand due to negligence, the publicity committee reserved the right not to redo the poster.
Unfortunately the Welfare Head was furious. She smsed me back and scolded me for many messages, saying how it had been my negligence and it was sheer audacity for me to accuse her of that, and how I would get into trouble if I did not redo the poster at once.
If you were in my shoes, what would you do to defuse the situation?
