Hello Mar,
Chennai is just opening up for callcenters market in comparison to other Hot places of India.NASSCOM rates Chennai as the Number One City for settingup Callcenters, the reasons attributed being cheap real estate prices, Low Cost of Living, Good INfrastructure both interms of Physical infrastructure and Telecom Infrastructure. When Meaning Telecom Infrastructure, Singtel Submerged Cables from Singapore in association with AirTel is landing in Chennai.
Related with Manpower good colleges churning out good english speaking candidates..
Now to the Negative Points of Chennai, since callcenters are just opening up the awareness levels among female candidates and acceptance to work in night shifts is comparatively less to the other cities.
As always with other cities, there has been some cases of smaller callcenters closing down operations due to various reasons, or struggling to operate.
As remarked by Kam Patel,
cochin is also booming as a nice place for callcenters. But i am not of the view that Labour Unions affect the functioning a callcenter.
thanks for allowing to express my views,
palani.
