World Class - Among the best in the world in any endeavor or category. "Lance Armstrong is a world class athlete." "Boeing in Seattle is a world class manufacturing facility." See Best in Class.
Wrongful Termination - Refers to a claim made by someone who is discharged from his or her employment for some reason other than a statutory violation, such as Title VII (race, color, creed), ADEA (age), or ADA (disability). Twenty years ago, employees were viewed as being "at-will," i.e., they could be fired for good reason, bad reason, or no reason at all, so long as not for a discriminatory reason. Now, many states have passed laws that you can only discharge employees for "cause" (illegal acts).
In other states there have been judicial inroads to provide employees protection against "public policy wrongful discharge." For example, you can't fire an employee for seeking workers compensation benefits. Employment attorneys still counsel employers to put in their handbook or policy manual that employees are "at-will" and can be terminated at any time for any reason.
