I have just signed a contract with a big mistake in it on the agencies behalf. Assuming they sign and return it to me, can I invoice for my full hourly rate as stated on the contract? Put it this way. I work on a day rate (regardless of hours) but it seems in my contract, the agency has put my full rate as an hourly rate. I'm under the impression this is a legal contract so it could be rather fruitful for me? (in a very seedy and underhanded way!)
