The area of Sylhet has over 150 gardens including three of the largest tea gardens in the world. Nearly 300,000 workers are employed on the tea estates of which over 75% are women. The tea plantation workers in Sylhet are mostly ethnic groups. Unaware of their right, they are passing their lives as slaves of cultured people.
