Directions: Answer the given question based on the following passage:
A calm, rational, socially sensitive approach was required to deal with most work related problems. To make good decisions people needed a peaceful mind. Heightened pressure increased their agitation, excitability and fight and flight response, which was hardly required to handle corporate situations calling for cool, calculated, well thought-out decisions. Adrenaline, which heightened their fight or flight response made them aggressive. The workplace was based on human inter-relation and team work which were quickly shattered by an aggressive approach. In situations where each person felt threatened and remained concerned about his own survival he was less likely to think of what his behaviour was doing to others.
What is the underlying idea of the passage?
