Collect news items about handloom workers and cotton growers. Analyse one news item in your own way. (Information Skills and Projects) 8M
Answer:
Handloom workers – the life is miserable March 16 – Pochampalli: Handloom workers in the state are facing lot of burdens. Since they are accustomed only to handloom industry, they are not able to find any other suitable livelihood to feed the family. Middlemen make selfish business by cheating the labourers at work places. Handloom workers spend their whole time at the work. But getting wages is very less.

It is not enough to fulfill the family needs. Interestingly, retail business men also see profit as middlemen bring lot of work through unauthorised marketing. The union of handloom workers urged the government to take necessary action in favour of hiking their daily wages. They also insisted to see transparent business which brings at least sharing in the profit from the handloom industry owners.

Time should help the cotton growers :
April 17 – Gadwal : Cotton growers have had bitter experiences due to unfavourable weather conditions and lack of support from the government. Middle men and some brokers cheat the farmers by not giving the profitable price for the harvested cotton. Unfair activities to earn the money becomes main motto of raw material buyers. They buy the harvested crop at low cost, but they sell it to the price which is two times more than the price paid to farmers. In this way the farmers are cheated. Many times, farmers requested the government to help them.

Analysis on the report:
If handloom department encourages the workers they will renew their life. Middle men dealing should be abolished which will bring the profit up in favour of labourers. Government should help the workers by providing facilities such as free education to the children, free health insurance scheme etc. Government should take authentic steps to do business by the workers through which they rejuvenate their livelihood.

The handloom weaving is an old tradition. The tradition and techniques used by weavers produce finest quality textiles which machine made textiles can not give. Yet, the handloom sector is facing a lot of problems. The government efforts to restructure handlooms are to be appreciated.
