Team Players? Or Business Wreckers?

In an emasculate field of businesses all over the world, a team player is the criteria of description that most businesses asked for before one gets employed.

One must be a team player, an individual with the team playing mode.

And some individuals enter establishment of companies to add diverse roles to the game but no team players or team work is in effect, none is present, or presented as it's just a business with much confusion and pretense of employment ways.

Where is the team players? As it seems that everyone is for themselves.

Everyone wants to be a boss of somebody and some used their title of authority to harass others.

So I am asking some companies, Where is the team for the team playing? And Why is everyone for themselves?

Some always feel intimidated when new staff arrives, and some try to use their title of authority to intimidate new staff, Why?

Why the dysfunction, why the call for team players when in most of the companies it's all about pretense?
