The work situation in India is pretty weird. You have to get permission from the company to quit your job (relieving letter). You can't work for another company unless you can present that letter which basically means they have a kind of slavery going on.
Then you have situations where workers can essentially get away with kidnapping management unless their demands are met. It's all very very strange. One of these days I need to look up the history to see how they came to think all this was a good idea.
