I am little bit confused about English grammar structure about "Have had to" and its uses and needed some clarification on the same.
For example:
I have had to take a leave.
Is it grammatically correct? If yes then what does it mean?
If not then what grammar structure should I use to show my compulsion for taking a leave against my will? I.e. I don't want to take a leave but my circumstances are making me to take a leave.
