Thanks for your input guys.

There is not any sort of  rule for vacation. I have 22 days for this year. Due to downsize of company, less personnel are working. so, it is kind of tough timing to go on vacation.


I think my question was not too clear-- I was looking for some points/reasons to attend on sibling's wedding. Since it is not mine, the wedding can go on regardless of my presence. So, why would you want/need to participate in that function?
