资料：Placing the right type of workers in close proximity to each other can generate up to a 15 percent increase in organizational performance，according to the study from Cornerstone On Demand，a provider of cloud-based learning and talent-management software，and researchers at Harvard Business School in Massachusetts. For businesses with 2，000 employees, this translates into an additional $1 million in profit each year，the study said.
For the study，researchers examined data from a two-year period of more than 2，000 employees working at a large technology company with locations in the U.S. and Europe. The study’s authors separated workers into three different categories based on the work they produced：
Productive： These employees are very productive，but don’t always produce quality work.
Quality：These workers produce work of superior quality，but aren’t always productive.
Generalists： These employees are average in terms of both productivity and quality.
The researchers defined productivity by how long it takes an employee to finish a task，and effectiveness by how often employees need to ask a co-worker for help completing a task.

What is NOT true about the categories of the workers？

A.There is no particular order of these categories
B.Generalists are those who are neither productive nor effective
C.The frequency employees need to ask a co-worker for help completing a task is recorded as effectiveness

The Worker 's Role in Management
Traditionally,it has been the workers'role to work and management's role to manage.Managers have planned and directed the firm's operations with little thought of consulting the labor force.Managers have rarely felt compelled（被迫的）to obtain the workers ' opinions or to explain their decisions to their employees.At most,companies have provided"suggestion boxes"in which workers could place ideas for improving procedures.In recent years,however,many management specialists have been arguing that workers are more than sellers of labor-they have a vital stake in the company and may be able to make significant contributions to its management.Furthermore,major company decisions profoundly affect workers and their dependents.This is
particularly true of plant closings,which may put thousands on the unemployment lines.Should workers, then,play a stronger role in management?
Workers should have a role in management.At the very least,the labor force should be informed of major policy decisions(A common complaint among rank-and-file workers is the lack of information about company policies and actions).Between 1980 and 1985 about five million workers were the victims of plant closings and permanent layoffs（失业）,often with no warning.At least 90 days'notice ought to be given in such instances so that workers have time to adjust.Management should consult workers before closing a plant,because the workers might be able to suggest ways of improving productivity and reducing costs and might be willing to make concessions that will help keep the plant operating.
It should become a general practice to include workers in some managerial decision making.There ought to be representatives of the workers on the firm's board of directors or other major policymaking groups.If rank-and-file workers are given a voice in the planning and management of the work flow,they will help to make improvements,their morale will rise,and their productivity will increase.As a further incentive,they must be given a share in the company's profits.This can be done through employee stock-ownership plans,bonuses,or rewards for efficiency and productivity.Finally,when a plant can no longer operate at a profit,the workers should be given the opportunity to purchase the plant and run it themselves.

According to the passage,what happened between 1980 and 1985?
A:Managers consulted workers before closing a plant.
B:Workers did not make necessary concessions.
C:About five million workers were laid off without advance notice.
D:Many companies were closed because of strikes.
