Out of country on holidays and JSB

I understand that Social Welfare allow you to be out of country for 12 days on holidays over 12 month period if you are claiming JSB and you have to inform them of this - right?

What happens if you are out of country for longer than this over the course of maybe a couple of trips e.g. say 4 individual 5 day trips at various times of the year totalling 20 days in total

What impact is there for JSB and SW in something like this where you exceeding SW quota of days ?

What if you dont tell them you going to be away?
Thanks

If you take more than the 12 days permitted by JSB, you don't get paid for the rest of the days you take.
