The mentality there is have the contract signed first and the changes come AFTER you startet working. It is not the same mentality like the round eyes long nosed occupants of the Globe: We negotiate to the bones and bring it to paper, then we sign and honour the written consent to the bone.
And the grass is always greener on the other side...i got ripped off by those round eyes long nosed people as you call them....the flat eyes,flat nose so far gave me EXACTLY what i signed for plus unwritten extras....plus 2pay rise,3rd on the way.
It depends who you work for in whatever region of the world...
