I have been invited to an interview and they say they are contacting my previous and current employer already. It's slightly strange to want this before.
It did say on the application form "please write down two references we can contact now. One must be your current employer" I thought oh well surely the won't ask my current employer they just mean my previous.
Apart from being obvious and common sense .. a bad idea to write to a current employer that you're thinking of leaving and potentially of putting to join this company, did I indirectly give permission?
