By Ruma Paul DHAKA, Nov 2 (Reuters) - Bangladesh's garment factories reopened on Monday after widespread closures and production disruptions a day earlier, but manufacturers remain concerned. Garment workers demand higher wages as Bangladesh forms a new wage board following widespread protests and unrest in the industry. Bangladesh garment workers are demanding a minimum monthly wage of 30,000 taka, more than double the current rate, as rising living costs fuel violent protests.
