I agree with this statement. I think that the workers are more satisfied when they have many different types of tasks to do during the workday than when they do similar tasks all day long.

Do similar tasks all day along have lots of defects. There is a science report about people's brain shows that if a people concentrate in one or similar task or a long time, his efficiency will get lower than at first. For example, at last Sunday, the day before our homework's deadline, I spent nearly the whole afternoon to finish my homework, but as the time flies, I began to feel boring and sleepy, so my efficiency got lower and lower. And at the next ,I was just get a grade B.So, In my opinion, I don't think do something similar all day long is a good choice and the workers won't be satisfied about it.

Though, do many different types of tasks to do during the workday have several strength. Doing colorful tasks can stimulate your interest of the work. And if you get the find that the works are interesting, you will be more and more efficient about the tasks. That is an example about my friend Tony. His study is really bad before, so I have an analyse about his study habit. Then I found that he likes study for one problem for a long time and always doesn't have any result. So, it is a low-efficiently way in my mind. And I convince him to attempt to do many different types of tasks to do during the workday
