Offenders will find that they will pay over the long run through decreased cooperation from colleagues. The first time a fellow worker takes credit for your ideas or work, privately confront the individual. Firmly inform him that you expect to be given credit for your work in the future. Should the situation recur, you will have to decide whether or not to press the issue with your supervisor. However, don't confuse a general attribution of credit to a project team with management giving others credit for your efforts.
Meetings are often too short to spend valuable time detailing each person's contribution.
Remember that you have a career, not just a job. After you learn how to execute your present responsibilities capably, begin learning what you will need to know for the next step up the company ladder. Develop important ancillary career skills. These include public speaking, effective writing, and computer expertise. If your company is foreign owned or has important foreign-operations, learn the appropriate foreign language.
