Lots of good advice here - definitely take action, initiate a discussion, and make your perspective clear, focused and positive - keeping in mind that being a PA and working your way up is a good thing; you can learn a lot from seeing how other people work in similar circumstances and (kmc307 aside) most of us can find great value in not being in charge right off the bat cuz (having trained a lot of "fresh outta school folks") there are many, many things they don't /can't teach you in college -
AND paperwork is a good thing on certain levels. Since SM training was learning on the job when I started, I found that running other people's copies was a great way to see how they took notes, what was left off, how to encourage reading between the lines for delicate issues - as well as why certain departments preferred one-sided or two-sided copies, etc, so now, when I stand there making my own copies (cuz, for many smaller companies, I too often have to stand at the altar of xerox) I can anticipate our needs accurately.
BUT I want to add one note to the mix, and that is attitude. HOW do you make copies? And I don't mean how do you lay the paper and hit the button, I mean what do you do while you stand there. Do you use the time to understand what you're copying and why? Do you chat up the assistant, the secretaries, the office staff (all of whom are valuable support to your career and often have great inside info that can help you take the next step). Do you do it before being asked, always with a smile and a winning attitude - not servile, but as an equal team member, an example of how capable and willing you are to help accomplish the shared goal? Do you take initiative when you think of something that might support the team? Regardless of how they percieve you now, if you do it because (to borrow a phrase) there are no small tasks, only small productions, and in theater everyone is equal and equally important, you can alter their perception to see you as an equal, an adult and someone who deserves a chance. It sound silly I know, but it's true - your attitude can make all the difference.
I totally get that you don't want to be the admin asst, and I totally get that they may not be ready to move you up (whether it's limited help or limited vision on their part) but a willingness doing whatever, fully and with a good attitude, can go a long way when you are trying to break in.
