Unfortunately the workplace is a little different, when compared to schools, colleges, and universities, who offer strict policies on plagiarism for students.
Don’t expect your employer to implement a plagiarism policy. Employers want team work and if you’ve ever been employed by anyone, you’ve probably heard the saying, “There is no I in team."
It is morally wrong for someone to steal your idea and present it as his own, however, in a work environment, if the idea, process or invention works, the employer is only happy with the outcome or a successful job well done. In reality, employers don’t want to mediate fights between co-workers; basically they will consider it a he said, she said situation.
Frustrating as it is, when it comes to workplace plagiarism, it’s best to be tactful, step back and find a way to be part of your initial idea—not enter into lengthy arguments—this only makes you look like a complainer, and employers want to avoid employee confrontation or level it at the get go so the office environment is a happy one.
