简述新生儿常见的几种特殊生理状态。

For some people, it’s easy to get dressed for work. Pilots and police officers, for example, don’t have to make decisions about their work clothes. They wear uniforms to work every day.

For many office workers, however, it is more difficult to choose clothes for work. They do not wear uniforms to the office. Also, many organizations are changing their dress codes. They are allowing their employees to wear casual(随意的) clothes to work.

The change to casual work clothes began in the 1990s. At first, many companies in the United States allowed employees to wear casual clothes on one day of the week—Friday. Friday became “Casual Friday” or “Dress-down Friday”. Today, however, many companies are allowing their employees to wear casual clothes every day of the week.

Some studies show that people are producing and achieving more when they are wearing comfortable clothes. Some companies also like the casual dress code because they don’t need to buy special clothes for work. They can save money this way.

Unfortunately, a casual dress code can also cause problems. Sometimes employees think they can wear anything. Many companies have rules about casual clothes. They list the kinds of clothes that are not “business-casual” clothes. Blue jeans, sandals, and sportswear are examples of clothes that are usually too casual for the office.
