I had personally witnessed ppl who were outcast.
Normally, there will be bullies in a company. They will want to
"keng" and want other ppl to do THEIR job.
If a guy do not want to do the kengsters job, the kengsters will
get together to bully the poor guy. Other ppl will just look on and
some will join in the bullying 'cos they themselves do not want to
be bullied. In the end the poor bloke will be ostracised.
