Still others have limited serf-images of what they can achieve, an image often shaped by a boss or an organization.
【B1】I believe the key to personal effectiveness at work (and to job satisfaction, also) is knowing what motivates us to perform. at our best. It's then up to us to seek opportunities to fulfill these motivations. When a job no longer motivates us, it's time to move on. Jobs have lifecycles, so take stock of where you are and decide if that's where you want to be. Consider the following.
1. Do you enjoy what you do.9 Nobody's excited about their job all the time, but you need to derive something from the work each day if you're going to perform. effectively. And money usually isn't a motivator. We're motivated by the desire to do good, to be effective, to connect with others, to be creative, or to make a difference. What really lights your fire? Have you gotten away from that in your work? You may have, yet not even know it.
2.Does your organization want you to realize your full potential? I believe many organizations lack the competence to develop or even keep good people. I've seen too many eases of individuals sent packing from organizations because they were more talented than their boss could stand, or because they did not always play by the company rules.
【B3】Also, prejudice and chauvinism still exist in the workplace. While we like to think women managers have achieved parity with men, this isn't true. The glass(some say concrete)ceiling still exists in many places. So, if you're a minority, consider how this is affecting your advancement chances. Don't be bitter, but do get busy. It may be time to get out and find something better.
3. Feel plateaued or pigeonholed in your job? Then look for ways to make your job a "learning-ground." Explore those informal, "out-of-the-box" ways we can keep growing professionally, even if we're suffering from a career slump, working for a tyrant, or "trapped" in a job that doesn't fully use our talents.
For example, find a way to increase responsibility at work (and in so doing, acquire some experience you've been longing to add to your resume). Or eager to be published? Then, write an article for a professional journal. Time to polish your oratorical skills? Speak at a professional conference or serve on the speaker's committee for your local ASTD Chapter.
【B3】There are always ways to leverage your professional experience, even ff that experience has been unpleasant. I know people who've written articles about sexual harassment based on their own negative experiences, then become stars on the speaking circuit because of it. Others have become consultants, specializing in areas they developed while employed by others.

Eastern District of New York Judge Jack B. Weinstein's 540-page opinion in Schwab v. Philip Morris USA, Inc. , 04-CIV-1945—which included an additional 965 pages of appendices for a total of 1,505 pages-gave tens of millions of smokers an avenue to recover damages from the nation's largest tobacco companies, including Philip Morris USA Inc. , R. J. Reynolds Tobacco Co. , Lorillard Tobacco Co. , and Liggett Group, Inc.
The class will include anyone who purchased light cigarettes from the time tobacco companies began selling them in the 1970s. The judge said he even would consider broadening the class, to encompass smokers of all "low tar" brands, not just light cigarettes. The judge suggested that an expansion of the class could assist the parties in negotiating a global settlement. He set a trial date for January 22, 2007. The plaintiffs intend to seek treble damages.
Weinstein has expressed skepticism about the plaintiffs' theory of damages, which alleges that light smokers were defrauded of billions because they believed they were buying a product of greater value because of its health advantages. The judge also questioned the size of the class, as well as the claim that as many as 90 percent of light cigarette smokers chose the cigarettes because they were less harmful.
In his ruling Monday, the judge stressed that while the suit was far from perfect, the evidence was sufficient. He said the jury system—which he described as the "ultimate focus group of the law"—was well equipped to sort out the particulars in accordance with Amendment VII of the U. S. Constitution.
Weinstein declined to grant an interlocutory appeal to the 2nd U. S. Circuit Court of Appeals. Theodore M. Grossman of Jones Day in Cleveland, which represents R J. Reynolds, said the defendants would seek a stay and appeal the class certification under Rule 23 (f) of the Federal Rules of Civil Procedure.
From the passage it can be inferred that "a $ 200 billion class action lawsuit" is one that ______.
A.requires a public fund of $ 200 billion
B.may lead to US $ 200 billion in payment
C.involves an investment of US $ 200 billion
D.is about what the tobacco industry is worth
