Expats considering working in Libya will almost certainly be pigeon-holed into employment by one of the hydrocarbon monstrosities that dominate the economy.  In a nation where 97 percent of export earnings are attributed to the country’s oil resources, foreigners may find working opportunities in Libya of varying description and degree, but the employers/sponsors will most likely be concentrated in sectors that seek to satisfy energy consumption.

Since sanctions were lifted in 2004, Libya has tried to encourage international investment and augment private sector participation to help with job creation and diversification, but the socialist-orientated government is hardly a global favourite.
 
Furthermore, Libyan leaders’ policies of control on prices, credit, trade and foreign exchange don’t exactly position it to make a fair play for more international money.  

Another main sector of employment in Libya is construction, which supports projects commissioned by the Organisation for the Development of Administrative Centres and other arms of government, such as the Ministry of Housing and the Ministry of Infrastructure. The telecommunications and NGO sectors are also significant expat employers.

Naturally, expat salaries vary, but are quite high relative to other remote expat destinations. Work permits and residency visas absolutely must be arranged prior to entry in the country. 

The usual working week is Sunday to Thursday.
