On a meeting today with peers and one other from my team most fairly senior managers not exec though. I asked a colleague to ensure he copied my director into some docs before a regular meeting so my director was briefed when this other person jumps quite strongly and says ' you should focus on getting your own shit together first the amount of time your area supplies documents late we haven't got time for this' it was quite aggressive and took everyone by surprise on the call. She them IM'd me copying one other in apologising for her outburst citing pressure from work. I explained that actually my area was often placed under pressure from seniors or customers to get items on the agenda last minute and it was outwith my control. Thing is the more I think about it the more I think its embarrassing and rude especially in front of my peers. I am angry and quite upset by the whole incident if I'm honest. Shes apologised should I just drop it?
