Answer to Question 1
Answer: Stress is the adverse reaction people have to excessive pressure placed on them from extraordinary demands, constraints, or opportunities. Stress is not always bad. Although it is often discussed in a negative context, stress does have a positive value, particularly when it offers a potential gain. However, stress is more often associated with constraints and demands. A constraint prevents an individual from doing what he desires. Demands refer to the loss of something desired. When an employee has his annual performance review at work, he feels stress because he confronts opportunity, constraints, and demands. A good performance review leads to a promotion, greater responsibilities, and a higher salary. But a poor review keeps him from getting the promotion. An extremely poor review might lead to his being fired.
Just because the conditions are right for stress to surface, however, does not always mean it will. Two conditions are necessary for potential stress to become actual stress. First, there must be uncertainty over the outcome, and second, the outcome must be important.
