There was a colleague, he finds ways and means to hijack other’s social capital, introduced to him. From the social media groups, a person might hijack the members and create a subgroup and becomes a leader. The politicians often do this on a large scale for votes.

There is another colleague, he will try to get a job through the recommendation made by you, after joining says negative things about you with the person that you have recommended to. Over a period brings the communication gap and hatred between you and the person recommended to.

There are some other colleagues who will say so many negative things about you and the people with whom you are working, and see that you will leave the place. After some time you will discover that the person has joined the same organisation and working with the same people comfortably.

Recently in democracy, political leaders are doing the same thing. Before elections, they criticise the opponent leader and shamelessly join the same leader after elections for money, favour and other positions.
