From my most recent job:
If you regularly exhibit incredibly annoying behavior or, lord forbid, actively tease or taunt someone, and you’re not instantly called on the carpet for it, this is not a sign that you have free reign to indulge in such unacceptable behavior for as long as you’re there. Nor does it mean that the company rules about a harmonious workplace and respect for others are empty bluster. Forget everything you learned in your anarchic hellhole of a high school and shape up immediately. Keep acting like a jerk and you will get shown the door, and you can forget about getting any kind of positive reference from anyone there.
If you’re not the kind of person who likes working with other people, or you’re not particularly diplomatic, or you hate to listen to other people’s grumbling, or you just have a lousy attitude, for crying out loud, don’t get a job requiring daily contact with customers. Even if you manage to avoid getting bounced within two weeks, you’ll be making hash of your mental health and well-being, and it’s never going to get any pleasanter.
If you’re doing something that’s really annoying to someone else, and you don’t consider it annoying, at least consider why it might be annoying and whether you should stop. Would it kill you to play the 12 Greatest Island Hits of '02 CD somewhat less than 200 times every freaking week??
It ain’t whinin’ if you have a legitimate beef. If someone’s mistreating you, or your environment is intolerable, or you feel threatened, bring it up with someone who can do something about it. Be polite, of course, but don’t just sit and suffer.
From my past jobs:
I don’t like those bitter, health-wrecking caffiene pills any more than you, but sometimes you just gotta take one for the team. It’s always good to have a few on hand for those times when you absolutely have to stay up and alert.
If you’re totally bored with your work, ask if you can do some other task that needs to be done. I often got out of endless reshelving, checking in, and checking out at the library by offering to clean the cubicles; not only was it a refreshing change of pace, I got to look at cubicles that didn’t have hideous stains and obscenities scrawled all over them.
Don’t guess. If a situation comes up that you’ve never seen before and have no idea how to handle, ask someone who’s done it before. Especially if you’re working with other people’s records.
