event planner with event conflict

[JenMarie]

I love my job and the flexibility it has because, as a trade off, I'm expected to be at all events at all hours of whatever day. So taking a vacation here and there or having a dr appointment during the slow times isn't that big of a deal.

So I got a call from my lil sis/best friend today and she tells me she is engaged and getting married at the end of September. She doesn't have a date set yet (just got engaged on Friday) BUT I already have a conflict at the end of September. The company camping trip.

Now, the camping trip is more of a morale booster for the company and falls in line with the Christmas party and whatnot, in terms of importance. But since I'm part of the marketing department and I have to plan a good chunk of it, I'm expected to be there, whether I like camping or not. (I already tried to opt out because I'm allergic to bug bites.)

So now that you have a backstory, when would you inform your employer that you may have an out of town wedding to go to on an event day that you are expected to be at. Like I said, I don't know when my friend's wedding is exactly... so this worry could be for nothing.

BUT I want to give plenty of notice to my employer so that can deal with out me or negotiate my job status (and buy plane tickets, whatnot.)

Or do I say anything at this point and let the chips fall where they may?
