I think I have told this story before. As it happens in some companies an undesirable element somehow slips thru the screening process and by the time they find out, he is already a union leader and practically 'untouchable'. And as I was new to the company, one such guy was quietly transferred to my department. Actually he behaved well but always a little grim. Then I got to know thru grapevine that he was a known criminal and he was barred from entering Bombay!
I was reminded of this story when I saw this headline a couple of days ago.
