I am <strike>about</strike> planning to join a Indian Software Company. But I am not comfortable with this one point.

How do I make them understand that I am not comfortable with Saturday's working.

I know, its not professional to agree to this point then simply flunk Saturday's anyway. Since its Officially off and they would pay me anyway(Well I am just assuming that they would pay).

**UPDATE:**
No I haven't signed any contract yet. I am looking forward to work with this company.
