Hello Jetkopite,
Where do you live? It is possible you travel for free on the NAS network to and from work. Not all duty starts at LGW can also be one of the three big Skandinavien cities, Charles de Gaulle or Barcelona. You have a minimum of 10 days off a month and you can request the off pattern for ex 5+5 or 6+4. The 10 days is a minimum but can also be more not less. Almost everybody commutes so it is possible.
Hope it helps!
