URGENT: Holidays while on Employment gap

[hbhatt]

I am on Tier 2 and have ILR due in few months. I have couple of questions for the experts.
----
1) If you have employment gap do you need to provide proof of that for ILR? If yes then what sort of proof is required?
----
2) Can you take holidays during employment gaps? Does this break your continues stay period?

Thanks in advance!
