I have been working on a project for three months. There are several other agencies involved on the project so naturally some areas will overlap. Bit of background, it's a project that has separate people covering print media, radio, television and online - I cover the online promotion, and sometimes we overlap with print media (eg, if a newspaper has a website).
Today I was asked (via email, copied to the team) by the project manager (my client) to list my targets for the coming months, which I immediately responded to with my targets. Five minutes later someone from the print media agency - we'll call him John - responded to one of my points saying, "Oh, sorry that target has already been done, I did it last week. I didn't know you were on the project." Or something to that effect.
The thing is, John should know very well that I was on the project, because I have been sending my updates to the entire team for the past several months (as is the normal practice). However, John is a bit hapless, and has already been reprimanded for not showing up to marketing meetings - had he shown up to yesterday's marketing meeting he would have been made even more aware that I was covering the online promotion. Often the print agencies will start targeting online media if their own reports are looking a bit slim, which is incredibly annoying because a) it makes it look like I'm not doing my job, and b) print lead times are much longer than online, which means a valuable bit of online coverage for my campaign ran several weeks too early because of this person's meddling.
So I responded to John's email, copying only the project managers (instead of the whole team - his original email was to the whole team) with the following:
"Thanks John. I think this would have had a better impact if had run a few weeks later and therefore closer to the event, but it's a great piece of coverage. Moving forward, let's keep in touch and coordinate our efforts."
I'm wavering between thinking I was rude for showing up John in front of the project manager, but at the same time, I think I could have been more firm with him - what I really felt like saying was "Actually, it's not ok, you've just blown an important part of my campaign and I'm going to have to put double the work because you stuck your nose into an area which you clearly know nothing about." But I know that definitely isn't polite.
I've been doing a great job on this campaign and my client is very happy with my work, but it's a relationship that was a bit shaky earlier this year - I actually had an identical situation when another print media agency "stole" one of my targets on a different project with this exact same client (the client took the other agency's side because I erroneously believed that responding "Hey, that's my work!" would have looked catty) so I am ESPECIALLY sensitive to this sort of thing.
