To Whom It May Concern,

I am writing this letter to express my complaint against the flaws of the electronic dictionary I bought from your shop last week.

The reason for my dissatisfaction is that there are two problems of the electronic dictionary. Firstly, when I received it, I found that its appearance had been scratched. Secondly, some of the keys on the keyboard do not work properly. Under these circumstances, I feel that you have not kept your promise posted on the homepage of your online store.

I strongly request that the effective measures should be taken to solve my problem. I appreciate it very much if you can either exchange a new one for me or refund me my money in full.

Thank you for your consideration and I am looking forward to hearing from you at your earliest convenience.

Sincerely yours,

Zhang Wei

The above table clearly shows us the statistics of employment satisfaction in a certain company. Most of people under 40 are unclear or dissatisfied with their work and 16.7% of them feel satisfied; 64% of those between 40 and 50 are not satisfied with their job and no one feel satisfied. 40% of people over the age of 50 feel content with their work, and compared with the other two groups, their satisfaction level is highest.

The reasons for this phenomenon may be listed as follows. First, middle-aged people from 41 to 50 face more pressure than people less than 40 or over 50. For example, they should support the family, both the children and the senior, so that they may consider their work only as a method of earning money and cannot enjoy it. Second, for those over the age of 50, burden is falling and thus satisfaction rate is rising.

In conclusion, the senior citizens, that is, people over 50, feel more content about their work than the young and the middle-aged. In my opinion, such a phenomenon must be paid attention to by the public, and proper and prompt actions should be launched by the young and the middle-aged to develop a healthy way of life and a positive outlook on life.
