Go to Facebook and get her vacation photos. Where her work was supposed to go, insert slides of her partying and yucking it up.

Do you have to check an email to find out your co-worker is not there? Have you no eyes? Is your co-worker invisible? have you no cake?.....Mmmm cake!... be right back.

Yeah, don't do her part for her. Do your bit, then let her get in trouble for not doing hers.

I'm sorry, but "being on vacation' is no excuse for not getting your stuff done, especially a work related project. If there's anything i learned in college is if someone hasn't done their part of a project, or just "forgot", you can bet i'm not adding their names on the project. Heck, even when i had my vacation time, i'd still get my projects done. Frankly, if i were in your shoes, I'd just do the missing work myself and just have my name and the other fellow collegues names ( if it was just you and her, then just keep it as your name) on the project. She's just competely irresponsible for not getting her half done. Let her get in trouble for her actions, don't take the fall for her OP.

I can't believe I'm doing this..... How long ago was her vacation approved, and when was this project assigned? I had a boss that used to give large work projects right before you went on vacation, expecting you to work while gone. If you didn't come back from holiday with the extra work done, your life would be miserable when you came back. Upper management and hr didn't care, because his numbers were good. I say we need more information.

Sounds like every college group project aha

I would blow her up. I would also take full credit for your presentation and when it goes well ask for a new person to work with.

WTF she can't do that? can't you postpone the presentation or have her do her part over email?

Sounds like a management screwup. Who approved her vacation on a week where she's supposed to give a presentation (or vice versa)?

I'll bet she did it on purpose
