Buyer beware!!
Those of you you have been here for a reasonable length of time will know that what is promised is sometimes vastly different to what is delivered! That is the nature of the beast.
If you believe the T's& C's as published (so far) then all I can say is to analyse the pro's and cons with a healthy scepticism before you commit yourself to 2 years of 'operational flexibility' requirements.
Those of you who are about to........ I salute you, as it will probably make my roster more enjoyable.
