Weekly holiday
Declaring two days weekly holiday is a good decision taken by the government for a country like Bangladesh, which is spending an enormous amount of foreign exchange for buying petrol and other related things in order to keep the country running. Moreover, the Dhaka city will get some respite from the poisonous gas and other related substances that it is swallowing everyday, especially from vehicles and urban based industries.
As for the economy, I believe the labourers will be greatly benefited as they will make some extra money by working on Saturdays as overtime.
