I can be given and taken.
When given, the giver is often forsaken.
I come in a garden variety and more,
but cannot be bought at your typical store.
When you can take me, you may well rejoice,
or you may have me without a choice.
If you don't have me, you may be a wall
if you're not found when superiors call.
What am I?
Hint:
A Sabbath, a long one, may well be me,
Or I might for your new motherhood be.
If you you are ill, I will come to your aid,
But those who take me won't always get paid!
