The work environment is one place where people find close friends as well as worst enemy.  There are also instances that a friendship is broken because of some unavoidable circumstances that both parties arrive at a certain point of no turning back but to sacrifice the friendship.

One factor that obviously destroys friendship is the way how promotions are being deliberated and both friends are competing each other for the position.  Well, this is if one of the parties could not be able to handle the pressure or no one is giving up for the sake of the other. Unless, of course, if both will give way because of friendship then this a good way of practicing and observing healthy and friendly working environment.

This part may, in the other way around, will affect the productivity of a certain individual who experience such situation because this will, for sure, take sometime before the hatred inside will cease.  Not to mention the possible separation of both parties, the work environment will no longer a good place to into.

This actually one of the reasons why there are such activities like training and seminar  for the employees to bridge and a friendly human relation in a certain institution.

Another factor that affects the supposed to be friendly working working environment is the malpractice of proper protocol in the implementation of reports especially in the manufacturing industry where workers need to participate properly in the production of the product.

Being tired and fatigue on work, there are times you could not control the temper and utter some unfriendly remarks to your co-worker.  Though it is hard to become cool, this is only the reason for everybody to become productive.
