TCS headcount reduction

Why would about 5000 employees leave a large employer in the IT industry, specially when it is passing through such an slowdown? Report in Taragana:

According to Hindustan Times, in the latest quarter TCS added a total of 2,828 employees with the total headcount of 1,43,761 at the start of the quarter. If the new hires are taken into consideration, the total employees strength should have reached 1,46,589 by the end of June. However, the firm’s headcount was at 1,41,642 as of June 30, 2009, showing a net reduction of 4,947 employees.

Isn't that strange?

I hope most of these folks are engaged in bringing new entrepreneurial ideas to life.
