All the BS I've seen recently with idiot engineers trying to be militant protectionists are just ensuring your own graves are dug really deep.
All the advantages you now receive, like sick pay, leave loadings etc, were fought for by people like me, if you don't want any of that then ring up your HR department tomorrow and insist that all these things be removed from your pay alone, the rest of us will keep them thanks. Bet ya dont make that phone call will ya??
