There are many ways to manage the organisational controversy with office colleagues .Manager can follow this step :

1.Manager can announce in the office, those who work hard he/she will get promotion as early as possible. Thus competition will increase between the employees.

2.Managers should keep silence when conflict arises and simply listen the problem.Thus employee will think that he is understanding the matter and he will definitely solve the problem. 

3.Manager can take him a private place or he can  take lunch with him and share the problem privately thus he can realise the problem easily and he will take it emotionally.

4. Manager can give him leadership place thus he can care about other employees and his own problem will solve out.

5.Some time manager should give importance to their decesion thus employees will give good response.
