Teamwork is all about working together to achieve a common goal or purpose. Is teamwork out of date? Why is it so hard to effectively conduct teamwork in those things?

One way we employ teamwork in everyday lives is by becoming a parent. It is a parent's job to teach their children and the basic skills and give them the knowledge they need to be successful in life. For example, the mother teaches her children manners and good health skills, while the father teaches them how to catch a ball or drive a car. However, in today's society, we find that more and more parents are experiencing that the teamwork is a one-sided thing. According to a report, there are 13.7 million single parents raising their children in the US and this could be due to the fact that parents don't take responsibility for their children, so they leave one parent to do it alone. This is a sad fact, but it reflects that effective teamwork is losing ground in the parenting aspect of our everyday lives.

Another place where teamwork affects us greatly is in our jobs. It doesn't matter if you are a small or large company; if you have at least one employee and yourself, then teamwork will be present. I have noticed that with the current economic recession（衰退期）, people are racing to grab jobs but the quality of people's work has gone down greatly. It just appears to me that people do not take pride in their work any more. They want to get to work as fast as they can, just to receive the paycheck, but their quality standards fly right out the window. So I think teamwork is losing its ground in the workforce. There are too many people who want to work independently and forget they are a part of a team.

As you can see, we run into the aspects of teamwork in just about everything we do. Do you believe teamwork is really losing ground in today's society? I think it is.
