This is a side effect of the mushrooming call centre industry...I personally feel the employees are treated like machines over there...the work condition is unhuman...they sit in so cramed space,they have 10-15 min break in between they have to sit 3-4 hrs at the strach & have to attend the call & this icident is Just addon on the whole situation....So I think this call centre industry will show its after effect in next 10-20 yrs when we will have very frastrated & seriously ill middle aged population...... thats it....
