44 At village AdiMahadkhadi in ShreeVardhan Taluka of Raigad District the work was held for about 5 to 6 month because the labour contractor has taken a huge amount of advance from the SMC and was not doing the work, we have called the SMC members and advised them to go to the contractor in a group of 10 to 15 members and pressurerize him to start the work and offered our support also the trick worked and finally the work was completed within 2-3 months.
