Refering to LABOUR PROTECTION ACT (No 7). , I would like to know the exact clause which defines: 

 

''Limitation of working offshore is not more than 28 days. For returning workers, the minimum rest day should be more than half the duration worked offshore.''

 

Example, 26 days worked offshore , 14 days rest before returning.

The word "offshore" appears nowhere in the page to which you have given a link.

I don't the info you are looking falls under any labor law.

I suspect it may fall under a regulation done by the Energy Ministry.

From where did you copy the above text?
