The thing is Emerald is a stepping stone for you say again, i wouldn't get so worked up about things. Just get the good old CV machine running and move on when you can, and until you do get a better offer why not just keep your head down, much safer!
I'm sure you are aware that operators like Emerald don't have masses of cash, start costing them too much or causing them problems and you may just end up out of a job. Better to be in paid employment and all that.
