Remember my very last post: The Market Is Not a Reverse Auction?
Whether you do or not, please allow me to give you a short recap:
Whatever one can say about the translation market in general, your part of it does not have to be the sum total of a bajillion outright auctions for the lowest bidder or recruitments based on 'best rates'.
You don't have to attune yourself to the market and passively obey the general trend, let alone go out of your way to adapt and fit in.
To adapt and fight is an option too.
Being active, making proposals, persuading, insisting, suggesting trade-offs, even declining unprofitable offers — is not something only clients and agencies can do.
You have as good a right to try and change the rules of the game as they do.
