You're not right in the head my friend. Do you imagine that someone somewhere has a crystal ball?.
If the companies they work for are reputable, then they will receive their salaries in due course for the days worked. Licenses may need to be sought by banks in countries which have put a block on foreign Libyan accounts - but other than that how can anyone tell?.
As for will salaries be doubled? - what planet are you from?. You're obviously NOT in Sirte as Libya has blocked internet access on the backbone - so why not better spend your time being concerned about all of the Libyans who have been affected by this trouble, rather than your own pocket!.
