There was a time when private companies/corporations based in Kolkata and branch offices of national and international companies especially Information Technology companies used to take pride in the low staff attrition rates prevalent in the Kolkata offices. This is partly due to limited job opportunities as a result of fewer companies and the tendency of most Bengalis to feel content with his or her life and current income.
The roots of the above issue which created a boon earlier has now created a bane. Companies find it difficult to expand operations due to poor availability of human capital. Many (maybe be most) commerce, arts, science and engineering graduates from this region planning to work move to other cities in India. Mangers find it hard to staff open positions with good resources and the work place continues to be boring with employees sharing a similar background.
