You may find out surprisingly your poker-faced manager is also nuts about karaoke, and the seemingly clumsy Johnny who is sitting to you in office is quite agile on the soccer field. You also got to know Anna, the HR assistant, is also a terrific cook by the delicate Lamb Roast dish that she brought to the group annual potluck party. You see things you usually can’t see in office. Your co-workers become more colorful and more human being like to you. They are no longer just Developer Robert, accountant Julia or QA Tim.
And they will also find the same way about you since it is also a great opportunity for you to show your personality and talents in these events.
The more people understand each other better, the better they will bond with each other. Friendship develops while frictions are diminished. People will be more happily work together and more willing to help each other out in difficulties. Thus the assignments and project will be done in a more efficient way. Of course your boss will become happier than ever.
