According to an ex RYR colleague, the Spanish authorities only allow " contractors" to work for a period of 2 years in this status..if NAS want to continue with these " contractors" one would presume they have to either: Have perm employment or move to bases outside of Spain..
Given many will reach the 2 year benchmark by Jan 2015 and the perm contracts are not likely to be on the table until end 2015, it would appear a " void" is on the horizon..?
