Woolley,
I'm not going to enter into the slanging match that you are so obviously chomping at the bit to start nor do I believe you are in a position to 'educate' me about rostering. You obviously don't appreciate real 'suffering', CAP371, if these are the regulations you work to, are there to protect 'real' suffering.
OK, you'll get some unsavoury duties along the way that you'd prefer not to do, but real suffering, don't make me laugh!
