7. Read the following excerpt and answer the questions that follow:
Appearance plays a tremendous role in determining how a communicator’s message will be received in business and elsewhere. As a rule, people who look attractive are considered to be likable and persuasive, and they generally have successful careers. For example, research suggests that beginning salaries increase about $ 2,000 for every 1 point increase on a 5 point attractiveness scale and that more attractive men(but not more attractive women) are given higher starting salaries than their less handsome counterparts.

A number of factors contribute to how attractive a person seems. For instance, potential employers, customers, and co-workers are usually impressed by people who are trim, muscular, and in good shape. One study, in fact, shows that people who are overweight have more trouble getting job offers. Some aspects of physical appearance cannot be changed very easily. One very significant factor in appearance, though – and one over which you may have the most control – is clothing.

The kind of clothing one wears can influence how people react. Boeing aircraft CEO Philip Condit is aware of this fact. Having discovered that discussions were hard to get going when he appeared in a business suit and tie, Conduit routinely dressed down when making trips to the shop floor to talk with the men and women who build Boeing aircraft.

Attitudes about what clothing is acceptable keep changing. By mid 1990s, even conservative IBM abandoned its decade long policy of requiring employees to wear a dark business suit, even allowing male workers in some jobs to show up for work without a suit and tie. A spokesperson for IBM explained, “You try to dress like your customers do.” But the casual dress trends brought on by the 1990 dot coms seem to be in decline.

Whether to dress up or dress down depends on several factors, including the industry or field of work. California’s outdoor gear clothing manufacturer, Patagonia, Inc., may have one of the most liberal dress codes: Even shoes aren’t required. By contrast, financial services and public administration businesses have some of the most conservative dress standards, while high tech, utilities, and natural resources tend to be the most informal.

1. Answer the following Questions [5 marks]
i) Why do attractive people generally have successful career?
ii) Why did Philip Conduit often change is usual style of dressing when he went to the shop floor?
iii) Who has the most conservative dress codes?
iv) Which is the aspect of appearance that you have a control on?
v) What influences people to react?

2. Say whether the following are true or false. [5 marks]
i) People who are attractive are generally not liked.
ii) IBM no longer expects its employees to come to office in business suits.
iii) People who are overweight have trouble in getting satisfactory jobs.
iv) Men and women in shop floor who build aircrafts dress in business suits.
v) California’s Patagonia, Inc., don’t believe in strict business dress codes.
