I am Pushparani. In Vizhithelu drama they are calling everyone as friend. The word friend applies to both male and female. The one who helps in difficult times is a friend. In the communist system, we call everyone as a friend (comrade). Sumathi explained very well about the meaning of union. Whether the worker is getting his PF, ESI and other benefits well. There is something called UAN number. Does the workers know about it? Many workers say that they don't know their PF number. But workers who are members in union they know their numbers.
