Every company has it's own corporate culture codes of behavior that help the group function as an efficient team says director of educational research.  Depending on the company's unique atmosphere it could take several weeks before you stop feeling like an alien and become truly acclimated.

Annoying Co workers

There's a group of annoying co workers who can make life in your workplace a living hell. Head on and spot some of your co workers shared by a book author:

• Loud talker.  You can be at one end of the office, and she's on the other end, and you hear every syllable she says.  Pity to those who have desk near this office bitch.
• Smoke club.  A  smelly group that teams up outside for a cigarette break.  Unless you want to be assaulted by nasty fumes, avoid sharing an elevator with these guys.
• The peacock.  This woman thinks she's on the fashion runaway and not in line to make copies.  She's strutting her stuff in the most attention-getting outfits.
• The Invisible worker.  Immune for working standard-eight-hour days, this offender has never seen 9 a.m. or 5 p.m. on the office clock- because he arrives late and leave early.
• Social Butterfly.  She  flits from one desk to another, eager to strike up conversations that promise to keep you from the more mundane tasks, like getting your work done.
• Stand off.  She talks too few, she acknowledge even fewer.  She can even look you in the eye.  She is an island unto herself.  May be she should stay that way.

Job adjustment

You can make the adjustment a smoother one by keeping the following points in mind:

• Don't expect the atmosphere of your new office to be the same as that of your former one. 
• Be friendly but not desperate.  Don't make the mistake of waiting for your coworkers to welcome you.  It's best if your boss walks you through the office on your first day, but if she's too busy, don't be shy about taking initiative.
• Listen more often than you talk.  Act like a spy:  Be extremely observant, ask of a lot of questions, and pay attention to the answers.
• Watch out for the outcasts workers.  Don't get too cozy with someone until you've identified the key players and discovered who's aligned with whom.  According to psychologists, the people who try to latch onto you right away are often the office outcasts.  But you may not find out until later, after you've been linked with them.
• Be active in company activities.  You can mix with people at many different levels of responsibility and become known in a broader way to the rest of the company.  Playing on the office volleyball team, or attending a lunch time lecture on an industry issue- all after opportunities for meeting your co workers and superiors and nurturing a sense of belonging.
• Stop complaining.   According to a book author the person the who says what else can I do will win points for being efficient.
• Be upbeat.  Be upbeat- within limits. Learn  to tame your behavior.  New employees need to walk a fine line-enthusiastic but not overeager, friendly but not desperate. If the challenge seems daunting, don't despair.  When co workers see you're willing to adopt, they'll nearly always lend a hand.
