Most industries in west Bengal Closed down in 1965-67 because they could not get any license, contracts, quota, permits from anti-Bengali politicians like Jagjivan Ram, Morarji Desai, YB Chavan, SK Patil, Bhutalingam etc etc. Only when the license-quota Raj has gone West Bengal is prospering with hundreds of companies lined up to invest. If the employers do not cheat why do the workers create trouble just to be unemployed, workers are not stupid. If you get your salary, no pension, no increments, no confirmation, you will also take out Lal Jhanda in no time.
