I've been part of the Indian corporate world for over a decade. In this decade, I have seen that, without exception, showing up at work when sick (particularly with fever) will get you rated as a star performer and great team player.
I always fail to understand how you are a team player if you can potentially make every other person fall ill or a star performer if your productivity is seriously compromised due to a fuzzy brain. Then again, such are the ways of the world...
Until ... H1N1 :-)
Somebody I know trooped in to work after having had a 102 F fever (no it wasn't H1N1) the previous evening and was asked to go back by the Project Manager for fear of passing it on to other people :-D
It took something like H1N1 to rock the foundation of Indian work culture. Does that say something?
