Not Deliveryman !

In Japan, shipping industry is especially traditionally done by men and women.  Generally speaking, most shipping agency are men. That's why this job needs a strong power to deliver heavy somethings such as furniture. Therefore, people think a power which a men has is stronger physically than a women. Actually, my father's job is shipping industry. When I was in childhood, he used to take me to his workshop. There are some women, but all of them was doing office work. However, I think the situation is changing today because there are more women involved in politics than old. Moreover, a woman's salary and a rate of employment are higher than a man. Why is that? A specialist says that employers hire women positively because a woman has more mind than a man in order to support their family and are more polite to customers than a man. In case that a customer is a women and a shipping agent is a woman, she can be more relieved than a man is that. I hope the range of woman's jobs expands more and more variable.
